Abstract:
A process for the preparation of certain cyano substituted esters and optical isomers thereof useful as insecticides by dehydration of the precursor carboxamido esters. Intermediates for the preparation of such compounds, e.g., racemic methyl 3-phenoxymandelate, methyl (S)-3-phenoxymandelate and methyl (R)-3-phenoxymandelate are also disclosed.
