Abstract

1,128,320. Dimerization of unsaturated nitriles. IMPERIAL CHEMICAL INDUSTRIES Ltd. 25 Aug., 1966 [16 Feb., 1966], No. 6801/66. Heading C2C. #-Alkyl-substituted α,#-olefinically unsaturated nitriles are dimerized employing a hydrocarbyl-substituted polyphosphine catalyst. The reaction is suitably effected at 0-200‹ C., preferably in the presence of 0À01 to 10 mole per cent of catalyst, optionally under an inert gas in the presence of a solvent, and a polymerization inhibitor, e.g. hydroquinone, may be present. In the examples, crotononitrile is dimerized to 1,3-dicyano-2-methyl-pentene-2 employing as catalysts tetramethyldiphosphine, 1,2-bis-(diphenyl phosphino) ethane, 1,6-bis- (diphenyl phosphino) hexane and o-phenylene bisdiethyl phosphine. Reference has been directed by the Comptroller to Specification 1,076,055.
