Copper‐photoredox‐catalysed C(sp3)–C(sp3) 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 catalysed by a copper/photoredox catalyst system. The approach is the first example of a cross‐coupling between BCP‐based reagents with alkyl electrophiles.
