An essentially mild and efficient catalyst system, the combined use of trimethylsilyl chloride and tin (II) chloride, is effectively employed for the activation of acetals, aldehydes, orthoesters, and α, β-unsaturated ketones to accomplish the reaction with silyl enol ethers to give the corresponding addition products in good yields.
