Description
Es wurde gefunden, daß man neue Substitutionsprodukte von aromatischen Kohlenwasserstoffen erhalten kann, wenn man diese mit Cyanacetylchlorid nach Friedel-Craft behandelt, d. h. mit sauren Kondensationsmitteln, wie z. B. Aluminiumchlorid, Eisenchlorid, bei mäßig erhöhten Temperaturen und gegebenenfalls in Gegenwart eines Lösungsmittels, wie z. B- Schwefelkohlenstoff, Acetylentetrachlorid u. dgl. Die Reaktion ist überraschend, denn Cyanacetylchlorid ist ein sehr unbeständiger Körper. Nach Angaben in der Literatur (M u 1 d e r Bl. [2] 29, 533) gelingt es nicht, das Säurechlorid sogar im Vakuum zu destillieren.It has been found that you can find new substitution products can be obtained from aromatic hydrocarbons if these are mixed with cyanoacetyl chloride according to Friedel-Craft treated, d. H. with acidic condensing agents, such as. B. aluminum chloride, ferric chloride, at moderately increased Temperatures and optionally in the presence of a solvent, such as. B- carbon disulfide, Acetylene tetrachloride and the like The reaction is surprising because cyanoacetyl chloride is a very volatile body. According to information in the literature (M u 1 d e r Bl. [2] 29, 533) it does not succeed in the acid chloride can even be distilled in vacuo.
Es war bei dieser Unbeständigkeit des Cyanacetylchlorids nicht zu erwarten, daß dieses sich mit Kohlenwasserstoffen zu wohl definierten Verbindungen kondensieren läßt, ohne sich zu zersetzen. Die Kondensation läßt sich mit sämtlichen aromatischen Kohlenwasserstoffen, beispielsweise der Benzol-, Naphthalin-, Acenaphthen- oder Anthracenreihe, ausführen. Die Reaktionsprodukte stellen wertvolle Zwischenprodukte für die Herstellung von Farbstoffen dar.Given this instability of cyanoacetyl chloride, it was not to be expected that this can be condensed with hydrocarbons to form well-defined compounds, without decomposing. The condensation can be carried out with all aromatic hydrocarbons, for example the benzene, naphthalene, acenaphthene or anthracene series. Put the reaction products valuable intermediate products for the production of dyes.
i. 150 Gewichtsteile Acenaphthen werden in 1000 Volumenteilen trockenem Schwefelkohlenstoff gelöst und mit ti 4 Gewichtsteilen Cyanacetylchlorid versetzt. In die Mischung werden nach und nach unter Kühlung 140 Gewichtsteile Aluminiumchlorid eingetragen. Nach i2stündigem Aufbewahren bei Zimmertemperatur wird 1I2 Stunde auf 400 erwärmt, dann wird das Reaktionsgemisch aufgearbeitet. · Das gebildete Substitutionsprodukt des Acenaphthens -von wahrscheinlich folgender Formeli. 150 parts by weight of acenaphthene are dissolved in 1000 parts by volume of dry carbon disulfide, and ti 4 parts by weight of cyanoacetyl chloride are added. 140 parts by weight of aluminum chloride are gradually introduced into the mixture with cooling. After storage for 12 hours at room temperature, 1 l is warmed to 40 0 for 2 hours, then the reaction mixture is worked up. · The formed substitution product of acenaphthene - probably of the following formula
H 2 C —■ O ΪΙ2H 2 C - ■ O ΪΙ2
kann aus Alkohol umkristallisieut werden und bildet dann nahezu farblose P-rismen. Es löst sich mit roter Farbe in konzentriertercan be recrystallized from alcohol and then forms almost colorless P-rises. It dissolves with red color in concentrated
