Abstract
The acyl cyanides (nitriles), notably benzoyl cyanide, are prepared by reacting an acid halide with an alkali metal cyanide, in an anhydrous solvent medium, in the presence of an alkylene oxide compound and a polar compound other than water, e.g., glycerol, ethylene glycol, formamide or a sugar derivative.
