effective catalyst for the hydrosilylation of alkyl phenyl ketones with methyldichlorosilane to give the corresponding silyl ethers of 1-phenylalkanols. In the case of dialkylketones, the reaction was accompanied by formation of silyl enol ethers in considerable amounts. Asymmetrichydrosilylation of a series of alkyl phenyl ketones catalyzed by chiral phosphine- platinum(II) complexes was undertaken
