The chemoselective cross-coupling of silylenolethers and allylic silanes to γ,δ-unsaturated ketones is achieved by the oxovanadium (V)-induced oxidative desilylation of the more readily oxidizable organosilicon compounds.

A highly efficient rhodium-catalyzed chemo- and regioselective addition of [small beta]-ketoacids to alkynes is reported. Applying a Rh(I)/(S,S)-DIOP catalyst system, [small delta], [gamma]-unsaturated ketones were prepared with exclusively branched selectivity under mild...
