Reactions of bis(chloromethyl)phosphinic(-phosphinothioic) chlorides with silylated carbamates and trimethylsilyl N-trimethylsilylacetimidoate

Bis(chloromethyl)phosphinic chloride reacts with trimethylsilyl methylcarba mate in benzene in the presence of a base to give trimethylsilyl bis(chloro methyl)phosphinate. The same reaction performed without a solvent and in th e absence of a base yields trimethylsilyl bis(chloromethyl)phosphinate and bis(chloromethyl)phosphinic anhydride. Reaction of bis(chloromethyl)phosphi nic chloride with trimethylsilyl diethylcarbamate yields N,N-diethylbis(chl oromethyl)phosphinic amide. The reaction of bis(chloromethyl)phosphinic (-p hosphinothioic) chlorides with trimethylsilyl N-trimethylsilylacetimidoate was studied.
