favorable elimination of Me/sub 3/SiOMe from Me/sub 3/SiSiMe/sub 2/CH/sub 2/OMe does not occur. From kinetic studies and trapping experiments, this is found to be due to a more favorable A-factor for three-centeredelimination of :CH/sub 2/. Three-centeredelimination of Me/sub 3/SiOMe from an sp/sup 2/-hybridized carbon to afford a vinylidene is found to be more facile than the analogous elimination from
