Merging Photocatalysis with Electrochemistry: The Dawn of a new Alliance in Organic Synthesis

The merging of a homogeneous photocatalytic system with an electrochemical cell, having exchanged electrons as the only common point, has been recently demonstrated. This combination opens unexplored pathways in synthesis and allowed net-oxidative photocatalytic processes to be realized in the absence of a chemical oxidant, including: 1) the C−H alkylation of heteroarenes and 2) the coupling of azoles with arenes in the presence of an electrogenerated photocatalyst.
