The energetic limitations of visible light can be circumvented by electrochemically priming a photocatalyst prior to excitation. This method enables the use of aryl chlorides with reduction potentials hundreds of millivolts beyond the potential of Na0 in carbon-carbon and carbon-heteroatom bond-forming reactions.
