Abstract
[GRAPHICS] Lewis acid-catalyzed reaction of allyl and benzyl trichloroacetimidates wit h alpha-silyl alcohols was found to be a general method for the synthesis o f alpha-alkoxysllanes. Upon exposure to CsF, these alpha-alkoxysilanes coul d be made to undergo [2,3]-Wittig rearrangement with an efficiency similar to that realized by the analogous but inherently more toxic alpha-alkoxysta nnanes.
