Abstract
1527966 Acyl cyanides DEUTSCHE GOLD – UND SILBER SCHEIDEANSTALT 3 June 1977 [25 Feb 1977] 23666/77 Heading C2C Acyl cyanides of the formula wherein R is a substituted phenyl group or an optionally substituted C 1-18 alkyl, C 3-8 cycloalkyl, naphthyl or heterocyclyl group, are obtained by reacting acyl halides (RCOX where X is a chlorine or bromine atom) with cuprous cyanide, the reaction being carried out in a mixture of 1 to 10 parts by weight of an inert carboxylic acid nitrile and 0À5 to 20 parts by weight of an inert organic solvent, at 50 to 180 C. Novel acyl cyanides of the formula may be obtained by the above process.
