Recent Advances in Visible Light Induced Palladium Catalysis

Visible light-induced Pd catalysis has emerged as a promising subfield of photocatalysis. The hybrid nature of Pd radical species has enabled a wide array of radical-based transformations otherwise challenging or unknown via conventional Pd chemistry. In parallel to the ongoing pursuit of alternative, readily available radical precursors, notable discoveries have demonstrated that photoexcitation can alter not only oxidative addition but also other elementary steps. This Minireview highlights the recent progress in this area. Visible light-induced Pd catalysis typically operates through the transfer of a single electron. The resulting hybrid Pd radical species can participate in a range of radical-based transformations otherwise challenging or unknown via conventional 2-electron processes. This Minireview highlights the recent progress in this emerging area.image
