Reactions of (chloromethyl)phosphonic(-hosphinic) chlorides with trimethylalkoxy(-phenoxy, -dialkylamino)silanes are accompanied by elimination of trimethylchlorosilane and lead to formation of related substitution products. Reactions of bis(chloromethyl)phosphinic chloride and (chloromethyl)phosphinic dichloride with neutral and hydrogen silyl phosphites were studied. The reactions of bis(chloromethyl)phosphinic chloride with tris(trimethylsilyl)phosphite, diethyl trimethylsilyl phosphite, and bis(trimethylsilyl) hydrogen phosphite yield trimethylsilyl bis(chloromethyl)phosphinate. Similar reactions with (chloromethyl)phosphonic dichloride resulted in isolation of bis(trimethylsilyl) (chloromethyl)phosphonate.

The reactions of H-phosphonate diesters with trityl and benzyl halides were investigated using 31P NMR spectroscopy. It was found that extensive oxidation, which usually accompanies the formation of trityl- or p-nitrobenzylphosphonates from the corresponding alkyl bromides in the Michaelis-Becker reaction, can be considerably suppressed or completely eliminated by reacting p-nitrobenzyl or trityl bromides with diphenyl H-phosphonate in acetonitrile in the presence of DBU.
