Radical 1,2-aryl migration in α,α-diaryl allylic alcohols toward β-silyl ketones

Abstract

A copper-catalyzed radical 1,2-aryl migration in α,α-diaryl allylic alcohols is developed, leading to β-silyl carbonyl compounds in moderate to good yields. The migration of aryls with lower aromaticity is favored. This procedure features the employment of silanes as commercially available materials.
