Document Type and Number:
Japanese Patent JPS56166162
Kind Code:
A
Abstract:
A novel process for the preparation of acyl cyanides of the general formula R-CO-CN (I) wherein R represents an optionally substituted alkyl radical with 1 to 8 carbon atoms, an optionally substituted cycloalkyl radical with 3 to 12 carbon atoms, an optionally substituted aryl radical or an optionally substituted 5-membered or 6-membered heterocyclic radical, which can additionally be fused to a benzene ring, in which a carboxylic acid fluoride or the general formula R-CO-F (II) in which R has the abovementioned meaning is reacted with an alkali metal cyanide, optionally in the presence of a diluent, at a temperature between 10 DEG and 200 DEG C.
