Abstract
Dialkyl 1-trimethylsilyloxy allylphosphonates (3a-3f) were synthesized by a one-pot reaction of trialkyl phosphite (1), carbonyl compounds (2) and trimethylchlorosilane. The procedure was carried out under very mild conditions and was very easy to conduct. The structures of (3) were confirmed by IR, 1HNMR, 31P NMR and MS.
