Synthesis of phosphorus-substituted dialkylamides of organophosphorus acids, containing PCH2NP fragments

Reactions of [N-(trimethylsilyl)aminomethyl]phosphonates with organophosphorus acid chlorides was studied, which allowed to develop convenient synthetic approaches to novel phosphorus-substrituted dialkylamides of organophosphorus acids, including a PCH2NP fragment. Certain properties of the resulting compounds are presented.
