Graphical Abstract

We show a reductive cross-coupling reaction of bicyclo[1.1.1]pentyl (BCP)-thianthrenium reagents and alkyl bromides, which is catalyzed by a copper/photoredox catalyst system. The reaction provides a variety of BCP-alkylated products through the formation of a C(sp3)−C(sp3) bond.

Abstract

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.
