Reaction of (chloromethyl)phosphonic(-phosphinic) chlorides with silylatedprotic nucleophiles

Reactions of (chloromethyl)phosphonic(-phosphinic) chlorides with trimethyl alkoxy(-phenoxy, -dialkylamino)silanes are accompanied by elimination of tr imethylchlorosilane and lead to formation of related substitution products. Reactions of bis(chloromethyl)phosphinic chloride and (chloromethyl)phosph inic dichloride with neutral and hydrogen silyl phosphites were studied. Th e reactions of bis(chloromethyl)phosphinic chloride with tris(trimethylsily l)phosphite, diethyl trimethylsilyl phosphite, and bis(trimethylsilyl) hydr ogen phosphite yield trimethylsilyl bis(chloromethyl)phosphinate. Similar r eactions with (chloromethyl)phosphonic dichloride resulted in isolation of bis(trimethylsilyl) (chloromethyl)phosphonate.
