                                    1,4-Disilylation of α, β-unsaturated ketones proceeded with 1,1-dichloro-1-phenyl-2,2,2-trimethyldisilane in the presence of a phosphine-palladium catalyst in benzene. Treatment of the disilylation products with an excess of methyllithium generated β-silyl lithium enolates, of which hydrolysis and alkylation gave β-(phenyldimethylsilyl) ketones and anti β-silyl α-alkyl ketones, respectively.
