The reactions of aromaticketones with trialkyl(trifluorovinyl)silanes in the presence of fluoride ions were studied. The conditions for the selective addition of trialkyl(trifluorovinyl)silanes to the carbonyl function of aromaticketones in the presence of cesium fluoride and absence of any solvents to form the trifluorovinyl containing “silylated” alcohols have been worked out. The analogous reactions
