Here we report the application of readily prepared and available coumarin dyes for photoredox catalysis, which are able to mimic powerful reductant [Ir(III)] complexes. Coumarin derivatives 9 and 10 were employed as photoreductants in pinacol coupling and in other reactions, in the presence of Et3N as a sacrificial reducing agent. As the electronic, photophysical, and steric properties of coumarins
在这里,我们报告易于制备和可用的香豆素染料在光氧化还原催化中的应用,它们能够模拟强大的还原剂[Ir(III)]配合物。在Et 3 N作为牺牲还原剂的情况下,香豆素衍生物9和10在频哪醇偶联和其他反应中用作光还原剂。由于香豆素的电子,光物理和空间性质可以改变,因此可以预测对几类光氧化还原反应的广泛适用性。
