Copper-Photoredox-Catalyzed C(sp(3))-C(sp(3)) Reductive Cross-Coupling of Alkyl Bromides with BCP-Thianthrenium Reagents

Herein, we report a reductive cross-coupling reaction of bicyclo[1.1.1]pentyl (BCP)-thianthrenium reagents and alkyl bromides. The reaction is catalyzed by a copper/photoredox catalyst system. The approach is the first example of a cross-coupling between BCP-based reagents with alkyl electrophiles.
