Transmetalation of 1-triorganosilyloxyvinyltin derivatives occurs with a reverse Brook rearrangement. Subsequent trapping with various electrophiles affords new acylsilanes.

A new methodology is described for the synthesis of enol esters of acylsilanes, from readily available vinyl esters. A solution of LDA is added to a mixture of an enol ester (preferably sterically congested, with only one α- carboxyl proton, eg 2-ethylhexanoate) and a chlorosilane at −78°C to afford the product.
