the corresponding deoxygenativechlorination products, in which the carbonyl carbon accepted two nucleophiles (H and Cl) with releasing oxygen. Only In(OH)3 catalyzed the reaction, and typical Lewis acids such as TiCl4, AlCl3, and BF3.OEt2 showed no catalytic activity. The reaction mechanism of this deoxygenativechlorination includes initial hydrosilylation followed by chlorination. Other nucleophiles
