Abstract

Abstract Silicon-containing chloromethylphosphorylated ureas undergo transformation involving evolution of chlorotrimethylsilane and formation of 1, 3, 4-oxazaphospholes. Their analogs, silicon-containing phosphorylated acylamides, transform in another way, viz. by β- cleavage to form the corresponding siloxyphosphonates. Quantum-chemical investigation of thermodynamic characteristics of these processes was carried out.
