Abstract
Abstract Functionalization of unactivated C−H bonds is a highly desirable process in organic chemistry as it gives direct access to new functional groups in a single step. This process is generally achieved using transition metal catalysts, and among them, palladium plays an important role due to its unique reactivity. Recently, photoredox catalysis has witnessed a huge surge, and many new and valuable organic reactions are uncovered periodically. Dual transition metal – photoredox catalysis on the other hand, has taken organic synthesis to new heights by achieving transformations that were previously not possible or difficult to achieve by both forms of catalysis independently. In this direction, many new and interesting dual palladium‐photoredox catalyzed C−H functionalization reactions combining the synergistic effects of both palladium and photoredox have been reported in the past few years, and it is imperative to summarize these reactions for further developments in this area.
