Synthesis of 0,0-dialkyl phthalimidophosphonothioates and dialkyl phthalimidophosphonates

Dialkyl phthalimidophosphonites were reacted with sulfur to synthesize 0,0-dialkyl phthalimidophosphonothioates. Reaction of phthalimide with trialkyl phosphites in carbon tetrachloride gives dialkyl phthalimidophosphonates.

Preparation of O,O-dialkyl phthalimido-phosphonothioate

The present invention is directed to an improved method for preparing O,O-dialkyl phthalimidophosphonothioate (hereinafter alternatively referred to as "phosphonothioate"), corresponding to the formula STR1 wherein each R is independently an alkyl group having from 1 to 4 carbon atoms, comprising reacting O,O-dialkyl phosphoramidothioate with phthalic anhydride in the presence of a tertiary amine catalyst.
