Photoredox Catalysis for Silyl‐Mediated C–H Alkylation of Heterocycles with Non‐Activated Alkyl Bromides

Abstract

The development of a Minisci reaction of electron‐deficient heteroarenes with non‐activated alkyl bromides under visible‐light photoredox catalysis is disclosed. Optimization of the reaction led to identification of mild, general, and practical reaction conditions compatible with sensitive functional groups. The scope of this transformation allowed late‐stage functionalization of pharmaceutical products containing electron‐deficient heteroarenes in a parallel fashion.
