of equimolar amounts of (bromomethyl)phosphonic dichloride and phenol gives phenyl (bromomethyl)chlorophosphonate. Its reactions with heptamethyldisilazane, N,O -bis(trimethylsilyl)acetamide, and potassium thiocyanate, leading respectively to a silylamidophosphonate, a silyl phosphonate, and an isothiocyanatophosphonate, were studied. (Bromomethyl)(chloromethyl)phosphinoyl isocyanate was synthesized

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 beta-cleavage to form the corresponding siloxyphosphonates. Quantum-chemical investigation of thermodynamic characteristics of these processes was carried out.
