Copper-catalyzed alkylarylation of vinylarenes with cycloalkylsilyl peroxides and boronic acids†
Abstract
A mild copper-catalyzed alkylarylation of vinylarenes with cycloalkylsilyl peroxides and boronic acids is described. This three-component protocol provides a straightforward approach to the remote keto-functionalized 1,1-diarylmethane derivatives. A radical pathway initiated by C–C bond cleavage is proposed for this tandem reaction.
