Copper-catalyzed silylperoxidation reaction of α,β-unsaturated ketones, esters, amides, and conjugated enynes

A synthetic method of copper-catalyzed silylperoxidation of α,β-unsaturated carbonyl compounds and conjugated enynes has been developed. The realization of silylperoxidation of the carboncarbon double bond permits direct access to silicon-containing peroxy products in moderate to good yields. Furthermore, this protocol distinguishes itself by operational simplicity and exhibiting good tolerance of a wide scope of functional groups. This strategy provides an efficient approach to the 1,2-difunctionalization of α,β-unsaturated carbonyl compounds and conjugated enynes.
