Abstract

Benzoyl cyanide is prepared by reacting benzoyl chloride and an alkali metal cyanide at elevated temperatures in an inert organic solvent in the presence of benzoic anhydride and/or substances which form benzoic anhydride with benzoyl chloride. The process produces pure, virtually dimer-free benzoyl cyanide in a surprisingly high yield of at least 90%.
