Photoredox-catalyzed radical–radical cross coupling of ketyl radicals with unstabilized primary alkyl radicals

Abstract

Herein, a novel protocol dealing with the preparation of sterically hindered alcohols has been successfully developed via radical–radical coupling reactions enabled by mild and redox-neutral photocatalysis. With alkylsilicates as the radical precursors, a range of primary alkyl radicals bearing various functional groups could couple with a range of phthalimides and activated ketones.
