Reductive Electrophotocatalysis: Merging Electricity and Light to Achieve Extreme Reduction Potentials

revised on 08.10.2019, 00:53 and posted on 08.10.2019, 16:55 by Hyunwoo Kim, Hyungjun Kim, Tristan Lambert, Song Lin
We describe a new electrophotocatalytic strategy that harnesses the power of light and electricity to generate an excited radical anion with a reducing potential of –3.2 V vs. SCE, which can be used to activate substrates with very high reduction potentials (Ered ~ –1.9 to –2.9 V). The resultant aryl radicals can be engaged in various synthetically useful transformations to furnish arylboronate, arylstannane, and biaryl products.
