Description

本発明は金属触媒及びその製造方法に関する。特に、創薬化学や有機合成化学に用いられる遷移金属触媒及びその製造方法に関する。   The present invention relates to a metal catalyst and a method for producing the same. In particular, it relates to a transition metal catalyst used in drug discovery chemistry and organic synthetic chemistry, and a method for producing the same.

遷移金属触媒は、現在の創薬化学や有機合成化学において必要不可欠なものであると認識されている。その一方で、遷移金属触媒はその安全性、反応生成物に残存する微量遷移金属の除去、廃液処理等が問題となる場合がある。近年高まっている環境調和型プロセス開発を目指す社会的要請を鑑みると、現在の遷移金属触媒が有する諸問題を解決しうる新たな遷移金属触媒の開発が要請されている。   Transition metal catalysts are recognized as essential in current drug discovery chemistry and organic synthetic chemistry. On the other hand, the safety of transition metal catalysts, removal of trace amounts of transition metals remaining in reaction products, waste liquid treatment, and the like may be problematic. In view of the increasing social demand for environmentally conscious process development in recent years, there is a demand for the development of a new transition metal catalyst that can solve the problems of current transition metal catalysts.

上述の問題の解決策の一つとして、本発明者らは以下の非特許文献1に示すとおり新規な遷移金属触媒の開発に世界で初めて成功した。
Arisawa et al., Jpn. J. Appl. Phys. 2002,41, L1197-L1199
As one of the solutions to the above problems, the present inventors have succeeded in developing a new transition metal catalyst for the first time in the world as shown in Non-Patent Document 1 below.
Arisawa et al., Jpn. J. Appl. Phys. 2002, 41, L1197-L1199

即ち、上記非特許文献1に開示するとおり、本発明者らは、極高真空条件下、基板(半導体、金属、絶縁体)上に結合原子を均一に並べ、その上に遷移金属触媒を結合させることにより、より安定で、再利用可能な触媒活性を有する新規な遷移金属触媒の開発に成功した。本発明者らは、この新規な遷移金属触媒を「基板結合型遷移金属触媒」と呼んでいる。   That is, as disclosed in Non-Patent Document 1 above, the present inventors arranged bonding atoms uniformly on a substrate (semiconductor, metal, insulator) under an extremely high vacuum condition and bonded a transition metal catalyst thereon. As a result, a new transition metal catalyst having more stable and reusable catalytic activity was successfully developed. The present inventors refer to this novel transition metal catalyst as a “substrate-bound transition metal catalyst”.

また、上述の問題の解決策の一つとして、以下の非特許文献2に開示されるような高分子担持型パラジウム触媒も知られている。
Yamada et al., J. Org. Chem. 2003, 68,7733-7741
As one of the solutions to the above problem, a polymer-supported palladium catalyst as disclosed in Non-Patent Document 2 below is also known.
Yamada et al., J. Org. Chem. 2003, 68,7733-7741

しかしながら、上記非特許文献1に係る金属触媒は、極高真空条件が必須である等の量産化を阻む問題、また3回程度しか再利用できないという問題を抱えていた。また、上記非特許文献2に係る金属触媒は、形成加工が困難で、しかも均一系触媒に比べて活性が低いという問題を抱えていた。   However, the metal catalyst according to Non-Patent Document 1 has a problem that obstructs mass production, such as the necessity of extremely high vacuum conditions, and a problem that it can be reused only about three times. Further, the metal catalyst according to Non-Patent Document 2 has a problem that it is difficult to form and process and has a lower activity than a homogeneous catalyst.

そこで、本発明は、上述の問題を鑑みてなされたものであり、極高真空等の特別な製造条件を必要とせず、10回程度の再利用が可能であり、且つ形成加工が容易な金属触媒を提供するものである。   Therefore, the present invention has been made in view of the above-described problems, and does not require special manufacturing conditions such as ultrahigh vacuum, and can be reused about 10 times and is easy to form.

The obtained solution is brought into contact with each other, and the organometallic complex is bonded or adsorbed to the molecule or the atom. In the metal catalyst of the present invention, an organometallic complex is supported on the surface of the material by using a molecule having a functional group that binds or adsorbs to the material and a functional group that binds or adsorbs to the organometallic complex.

図1を参照する。図1には、本発明の金属触媒を製造するプロセスの一例が記載されている。本実施の形態においては、有機金属錯体と結合又は吸着する原子に硫黄を用いた例を示す。   Please refer to FIG. FIG. 1 describes an example of a process for producing the metal catalyst of the present invention. In this embodiment, an example in which sulfur is used for an atom that is bonded to or adsorbed to an organometallic complex is described.

まず、ガリウム砒素基板(13×11×0.6 mm)を多硫化アンモニウム(S content
5〜7%, 3.0 mL)に60℃で30分間浸し、ガリウム砒素基板を多硫化アンモニウムに接触させた後、水とアセトニトリルで洗浄した(図1(A))。このプロセスにより、硫黄(S)がガリウム砒素と結合又は吸着する
First, a gallium arsenide substrate (13 x 11 x 0.6 mm) was placed on ammonium polysulfide (S content
5-7%, 3.0 mL) at 60 ° C. for 30 minutes, the gallium arsenide substrate was brought into contact with ammonium polysulfide, and then washed with water and acetonitrile (FIG. 1 (A)). This process allows sulfur (S) to bind or adsorb to gallium arsenide.

その後、得られた基板を6 mmHgの減圧下室温で10分間真空乾燥し(図1(B))、更にヒートガン加熱下で20分間乾燥させ(図1(C))、硫黄(S)が結合又は吸着したガリウム砒素基板(S-GaAs)を得た(図1(D))。   After that, the obtained substrate is vacuum-dried at room temperature under a reduced pressure of 6 mmHg for 10 minutes (Fig. 1 (B)) and further dried for 20 minutes under heating with a heat gun (Fig. 1 (C)), and sulfur (S) is bonded. Alternatively, an adsorbed gallium arsenide substrate (S-GaAs) was obtained (FIG. 1D).

次に、硫黄が結合又は吸着したガリウム砒素基板(S-GaAs)を有機金属錯体であるテトラキストリフェニルフォスフィンパラジウム(Pd(PPh3)4)(25 mg)のアセトニトリル溶液(3.0 mL)中で12時間攪拌し、パラジウム(Pd)を結合又は吸着(0.2〜0.4 mg)させ、本発明の金属触媒を得た(図1(E))。そして、得られた基板をアセトニトリルからなる洗浄液に浸し、触媒活性が無くなるまで洗浄した(図1(F))。 Next, a gallium arsenide substrate (S-GaAs) bonded or adsorbed with sulfur in an acetonitrile solution (3.0 mL) of tetrakistriphenylphosphine palladium (Pd (PPh 3 ) 4 ) (25 mg), an organometallic complex. The mixture was stirred for 12 hours, and palladium (Pd) was bound or adsorbed (0.2 to 0.4 mg) to obtain the metal catalyst of the present invention (FIG. 1 (E)). Then, the obtained substrate was immersed in a cleaning solution made of acetonitrile and cleaned until the catalytic activity was lost (FIG. 1 (F)).

得られた金属触媒を以下の化学反応式に示す芳香族ハライドと二重結合とのカップリング反応(Heck反応)に用いた(図1(G))。結果を表1に示す。   The obtained metal catalyst was used in a coupling reaction (Heck reaction) between an aromatic halide and a double bond represented by the following chemical reaction formula (FIG. 1 (G)). The results are shown in Table 1.

Figure 2005270918
Figure 2005270918

Figure 2005270918
Figure 2005270918

表1に示すとおり、1回目の反応においては収率99%が得られた。同じ金属触媒を繰り返してHeck反応に用いると、2回目は収率90%、3回目は72%と収率が下がっていくものの、10回目の使用においても収率28%が得られ、10回目の使用においても実用に耐え得るものであることが確認された。   As shown in Table 1, a yield of 99% was obtained in the first reaction. When the same metal catalyst is repeatedly used for the Heck reaction, the yield decreases to 90% in the second time and 72% in the third time, but the yield decreases to 28% even in the tenth use. It was confirmed that the product can withstand practical use even when used.

ここで、比較のため、従来の均一系のテトラキストリフェニルフォスフィンパラジウム(Pd(PPh3)4)をHeck反応に用いたときの結果を表2に示す。 Here, for comparison, Table 2 shows the results when conventional homogeneous tetrakistriphenylphosphine palladium (Pd (PPh 3 ) 4 ) is used in the Heck reaction.

Figure 2005270918
Figure 2005270918

表2に示すとおり、従来の均一系のテトラキストリフェニルフォスフィンパラジウム(Pd(PPh3)4)を用いたHeck反応では、0.58 mgのテトラキストリフェニルフォスフィンパラジウムを使用した場合の収率は65%であり、0.0058
mgを使用した場合では収率が9%しか達成できないことが分かる。よって、本発明の金属触媒は、均一系の金属触媒よりも高活性で且つ高収率であることが確認された。
As shown in Table 2, in the conventional Heck reaction using homogeneous tetrakistriphenylphosphine palladium (Pd (PPh 3 ) 4 ), the yield when 0.58 mg of tetrakistriphenylphosphine palladium is used is 65. %, 0.0058
It can be seen that a yield of only 9% can be achieved when mg is used. Therefore, it was confirmed that the metal catalyst of the present invention has higher activity and higher yield than the homogeneous metal catalyst.

また、比較のため、何ら処理をしていないガリウム砒素基板(GaAs)、多硫化アンモニウム処理のみを施したガリウム砒素基板(S-GaAs)および多硫化アンモニウム処理を施さずにテトラキストリフェニルフォスフィンパラジウム(Pd(PPh3)4)によりパラジウムを吸着させたガリウム砒素基板(Pd-GaAs)を用意し、それらをHeck反応に用いた結果を表3に示す。なお、硫化アンモニウム処理を施さずにテトラキストリフェニルフォスフィンパラジウム(Pd(PPh3)4)によりパラジウムを吸着させたガリウム砒素基板(Pd-GaAs)の作製にあたっては、図1(E)及び(F)のプロセスと同様のプロセスを用いた。即ち、ガリウム砒素基板(S-GaAs)をテトラキストリフェニルフォスフィンパラジウム(Pd(PPh3)4)(25 mg)のアセトニトリル溶液(3.0 mL)中で12時間攪拌し、パラジウム(Pd)を結合又は吸着(0.2〜0.4 mg)させた後、得られた基板をアセトニトリルからなる洗浄液に浸し、触媒活性が無くなるまで洗浄した。 For comparison, a gallium arsenide substrate (GaAs) that has not been subjected to any treatment, a gallium arsenide substrate that has undergone only ammonium polysulfide treatment (S-GaAs), and tetrakistriphenylphosphine palladium that has not undergone ammonium polysulfide treatment. Table 3 shows the results of preparing gallium arsenide substrates (Pd-GaAs) on which palladium was adsorbed by (Pd (PPh 3 ) 4 ) and using them for the Heck reaction. In preparation of a gallium arsenide substrate (Pd-GaAs) in which palladium is adsorbed by tetrakistriphenylphosphine palladium (Pd (PPh 3 ) 4 ) without being subjected to ammonium sulfide treatment, FIGS. ) Was used. That is, a gallium arsenide substrate (S-GaAs) was stirred for 12 hours in acetonitrile solution (3.0 mL) of tetrakistriphenylphosphine palladium (Pd (PPh 3 ) 4 ) (25 mg) to bind palladium (Pd) or After adsorption (0.2 to 0.4 mg), the obtained substrate was immersed in a cleaning solution made of acetonitrile and washed until the catalytic activity was lost.

表3に示すとおり、何ら処理をしていないガリウム砒素基板(GaAs)および多硫化アンモニウム処理のみを施したガリウム砒素基板(S-GaAs)をHeck反応に用いた場合、反応は起こらなかった。一方、多硫化アンモニウム処理を施さずにパラジウムを直接結合させたガリウム砒素基板(Pd-GaAs)をHeck反応に用いた場合、1回目の反応においては収率77%が得られた。同じ基板を繰り返してHeck反応に用いると、2回目は収率70%、3回目は71%と収率が下がっていき、10回目の使用においては収率6%が得られたが、本実施例の金属触媒(Pd-S-GaAs)よりも繰り返し使用による収率の低下が見られた。このことから、本実施例の金属触媒においては、硫黄(S)が重要な役割を果たしていることが確認された。但し、多硫化アンモニウム処理を施さずにパラジウムを直接結合させたガリウム砒素基板(Pd-GaAs)であっても、十分な収率が得られることが確認された。   As shown in Table 3, when a gallium arsenide substrate (GaAs) not subjected to any treatment and a gallium arsenide substrate (S-GaAs) treated only with ammonium polysulfide was used for the Heck reaction, no reaction occurred. On the other hand, when a gallium arsenide substrate (Pd-GaAs) directly bonded with palladium without being subjected to ammonium polysulfide treatment was used for the Heck reaction, a yield of 77% was obtained in the first reaction. When the same substrate was repeatedly used for the Heck reaction, the yield decreased to 70% for the second time and 71% for the third time, and a yield of 6% was obtained for the 10th time. A decrease in yield due to repeated use was observed as compared with the metal catalyst of the example (Pd-S-GaAs). From this, it was confirmed that sulfur (S) plays an important role in the metal catalyst of this example. However, it was confirmed that a sufficient yield could be obtained even with a gallium arsenide substrate (Pd-GaAs) in which palladium was directly bonded without being subjected to ammonium polysulfide treatment.

次に、10回のHeck反応に使用した本実施例の金属触媒をアセトニトリルからなる洗浄液に浸し、触媒活性が無くなるまで洗浄し、再生処理を行った(図1(H))。そして、再生処理を施された金属触媒を再度Heck反応に用いた(図1(I))。結果を表4に示す   Next, the metal catalyst of this example used for 10 Heck reactions was immersed in a cleaning solution made of acetonitrile, washed until the catalytic activity disappeared, and regenerated (FIG. 1 (H)). Then, the regenerated metal catalyst was used again for the Heck reaction (FIG. 1 (I)). The results are shown in Table 4.

Figure 2005270918
Figure 2005270918

表4に示すとおり、1回目の反応においては収率89%が得られた。同じ金属触媒を繰り返してHeck反応に用いると、2回目は収率88%、3回目は85%と収率が下がっていくものの、10回目の使用においても収率30%が得られ、10回目の使用においても実用に耐え得るものであることが確認された。このことから、触媒活性の低下した本発明の金属触媒に化学的処置を施すことによって、再度金属触媒の材料へ十分な定着が可能であることが確認された。以上のように、本発明の金属触媒は、担体となる材料の再利用が可能であるという優れた効果を奏することが確認された。   As shown in Table 4, a yield of 89% was obtained in the first reaction. When the same metal catalyst is repeatedly used for the Heck reaction, the yield decreases to 88% in the second time and 85% in the third time, but the yield decreases to 30% even in the tenth use. It was confirmed that the product can withstand practical use even when used. From this, it was confirmed that the metal catalyst of the present invention with reduced catalytic activity can be sufficiently fixed to the metal catalyst material again by chemical treatment. As described above, it was confirmed that the metal catalyst of the present invention has an excellent effect that the material used as the carrier can be reused.

ここで、図2を参照する。図2には、XPS(X-ray
Photoelectron Spectroscopy:X線光電子分光法)による測定結果が示されている。図2において、AはHeck反応に用いる前の本実施例の金属触媒の測定結果を示し、Bは10回のHeck反応に使用した後の本実施例の金属触媒の測定結果を示し、またCは10回のHeck反応に使用した後の、多硫化アンモニウム処理を施さずにパラジウムを吸着させたガリウム砒素基板(Pd-GaAs)の測定結果を示している。
Reference is now made to FIG. Figure 2 shows XPS (X-ray
The measurement result by Photoelectron Spectroscopy (X-ray photoelectron spectroscopy) is shown. In FIG. 2, A shows the measurement result of the metal catalyst of this example before being used for the Heck reaction, B shows the measurement result of the metal catalyst of this example after being used for 10 times of the Heck reaction, and C Shows the measurement results of a gallium arsenide substrate (Pd-GaAs) on which palladium was adsorbed without being subjected to ammonium polysulfide treatment after being used for 10 Heck reactions.

図2のAに示されるとおり、Heck反応に用いる前の本実施例の金属触媒からは、パラジウムと燐(P)のコアレベルのシグナルが検出されており、GaAs基板からのシグナルは検出されていない。このことにより、本実施例の金属触媒においては、(Pd(PPh3)4)の層がGaAs基板の表面を完全に覆っていることが分かる。また、図2のBに示されるとおり、10回のHeck反応に使用した後の本実施の形態の金属触媒からは、パラジウムのシグナルが依然として検出されている。また、図2のCに示されるとおり、10回のHeck反応に使用した後の、多硫化アンモニウム処理を施さずにパラジウムを吸着させたガリウム砒素基板(Pd-GaAs)からは、パラジウムのシグナルが検出されなかった。これらの測定結果からも、(Pd(PPh3)4)の定着には、硫黄の終端が非常に重要な役割を果たしていることが確認された。 As shown in FIG. 2A, a core level signal of palladium and phosphorus (P) was detected from the metal catalyst of this example before being used for the Heck reaction, and a signal from the GaAs substrate was not detected. Absent. From this, it can be seen that in the metal catalyst of this example, the (Pd (PPh 3 ) 4 ) layer completely covers the surface of the GaAs substrate. Further, as shown in FIG. 2B, a palladium signal is still detected from the metal catalyst of the present embodiment after being used for 10 Heck reactions. In addition, as shown in FIG. 2C, the gallium arsenide substrate (Pd-GaAs) on which palladium has been adsorbed without being subjected to ammonium polysulfide treatment after being used for the Heck reaction 10 times has a palladium signal. Not detected. From these measurement results, it was also confirmed that the termination of sulfur plays a very important role in the establishment of (Pd (PPh 3 ) 4 ).

以上説明したとおり、本発明の金属触媒は、従来の均一系触媒や上述の非特許文献1に記載されている方法により合成した金属触媒と比較して活性が極めて高く、また10回程度の再利用が可能である。更に、本発明の金属触媒は、使用を繰り返すことにより活性が低下した場合であっても、化学的な再処理を施すことにより、再度金属を結合させることができ、再処理が可能であるという優れた効果を奏する。   As explained above, the metal catalyst of the present invention is extremely high in activity compared to conventional homogeneous catalysts and metal catalysts synthesized by the method described in Non-Patent Document 1 described above, and re-appeared about 10 times.
