Abstract
Process for the synthesis of acyl cyanides of formula: <IMAGE> in which R denotes an alkyl, cycloalkyl or aryl radical or a heterocyclic residue, consisting in reacting acyl halides of formula: <IMAGE> in which R has the above definition and X denotes a halogen, with alkali metal cyanides, characterised in that the reaction takes place in the presence of a product containing alkylene oxide units and in the presence of catalytic quantities of water.
