Process for preparing cyano substituted bezyl esters, partucularly of formula (I) n<CHEM>n 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 4 carbon atoms. The resulting benzyl esters are particularly useful as insecticides. |
