我们描述了一种新的电光催化策略，利用光和电的能量产生一个激发的自由基阴离子与还原电位为-3.2 V vs SCE，它可以用来激活基板具有非常高的还原电位（Ered-1.9至-2.9 V）。所得芳基可参与各种合成有用的转化以提供芳基硼酸酯、芳基锡烷和联芳基产物。
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.
