ABSTRACT:
Quaternary ammonium salts and sterically unhindered, nucleophilic, tertiary amines are novel cocatalysts which are used in the process of reacting an alkali metal phenate, pyridinate or pyrimidinate with an O,O-dialkylphosphorochloridothioate or O-alkyl phenylphosphonochloridothioate to produce the corresponding phosphorothioates and phenylphosphonothioates. The process is conducted under alkaline conditions in a liquid reaction medium.
