Treatment of various acyltrimethylsilanes with vinylmagnesium bromide has allowed a stoichiometric generation of the corresponding 3-(trimethyl-siloxy)allylmagnesiums, which, in the presence of copper(I) trimethylsilyl-acetylide, undergo conjugate addition to several enones to afford the corresponding 1,6-diketone derivatives in good yields.
