Process for preparing cyano substituted bezyl esters, par- tucularly of formula (I)
wherein R represents a substituted or unsubstituted aromatic group, Y represents hydrogen or cyano, and X represents halogen, which involves reacting an acid halide with an aldehyde and a water soluble cyanide in water in the presence of a tetraalkyl ammonium halide wherein each alkyl group contains from 1 to about carbon atoms. The resulting benzyl esters are particularly useful as insecticides.
