The Selective 1,2-Addition of Ketene Silyl Acetals to α,β-unsaturated Ketones Promoted by a Copper(I)-Phosphine Complex
The thermal reaction of an α,β-unsaturated ketones with a ketene silyl acetal in the presence of the copper(I)halide-phosphine complex brought about the selective formation of the products based on 1,2-addition, while use of the copper(I)halide alone afforded the 1,4-adduct type of product.
