Conjugate addition of arylsilanes to unsaturated carbonyl compounds catalyzed by rhodium in air and water.
ArSiCl3 and Ar2SiCl2, believed to be unstable in aqueous media, reacted efficiently with alpha,beta-unsaturated ketones and esters in air and water (in the presence of sodium fluoride and a rhodium catalyst), giving good to excellent yields of the desired conjugate addition products.
