Abstract
1,196,958. 2,2,6,6-tetra-alkyl piperidine nitroxides. SANKYO CO. Ltd. 11 July, 1967 [16 Aug., 1966; 5 Oct., 1966], No. 31858/67. Heading C2C. Novel compounds of the general formula wherein R 1 and R 2 are alkyl groups and R 3 and R 4 are each cyano, carboxyl, alkoxycarbonyl, carbamoyl, aliphatic or aromatic acyl groups or aryl groups are prepared by reacting a compound of the general formula with a compound R 3 -CH 2 -R 4 in the presence of a basic condensing agent. The compounds, except where R 3 and R 4 are cyano groups may also be prepared by reacting a 2,2-dimethyl 6,6-dialkyl-4-piperidone with a compound R 3 -CH 2 -R 4 and then treating the product with a peroxide. The basic catalyst may be a hydroxide or carbonate of an alkali metal, an alkaline earth hydroxide, alkali metal alcoholate alkali metal amide or hydride. The perioxide employed is preferably H 2 O 2 but may be an organic peracid, e.g. peracetic or perbenzoic acid. In the Examples 2,2,6,6-tetramethyl-4- oxopiperidine nitroxide is reacted with (1) benzyl cyanide (2) malononitrile, (3) ethyl cyanoacetate to give 4-(α-cyano-benzylidine)-, 4-(α,α-dicyanomethylene)-, and 4-(α-cyano-α- ethoxycarbonylmethylene)- 2,2,6,6.tetramethyl piperidine nitroxide respectively using the first procedure. The second method was employed to prepare 4-(α-carbamoylbenzlidene) -, 4- (α- carbamoyl - α - ethoxycarbonylmethylene)- and 4-(α,α-dicarbamoyl-methylene)- 2,2,6,6-tetramethyl piperidine nitroxide from 2,2,6,6- tetramethyl-4-piperidone. The starting material for the first method may be prepared from diacetone alcohol and a ketone of the formula R 1 R 2 C = O in the presence of NH 3 and a Lewis acid followed by treatment of the tetraalkyl-4-piperidone with H 2 O 2 or an organic peracid. The starting material for the second method, tetraalkyl-4- piperidone is prepared as described above.
