Functional derivatives of (bromomethyl)phosphonic acid

Reaction 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. Chemical properties of the prepared functionalyzed (bromomethyl)phosphonates were investigated.
