Rhodium-catalyzed acylation of vinylsilanes with acid anhydrides

A catalytic acylation of vinylsilane with acid anhydride is accomplished by the use of [RhCl(CO)(2)](2), in which the transmetalation between vinylsilane and rhodium(I) carbonyl complex plays a key role. The application of this acylation reaction to (1-acyloxyvinyl)silanes provides synthetic methods for alpha-acyloxy enones, alpha-diketones, and their derivatives.
