Dimethyl thiophosphite reacts with aliphatic aldehydes and ketones, Michael acceptors, and N-benzyl imines to afford excellent yields of alpha-hydroxy phosphonothionates, beta-substituted phosphonothionates and alpha-amino phosphonothionates, respectively. Dealkylation of alpha-amino phosphonothionates affords N-benzyl alpha-amino phosphonothioic acids. Dimethyl thiophosphite reacts with electrophiles at a significantly greater rate than dimethyl phosphite.[GRAPHICS]
