complexes, Ir(ppy)3 proved to be the best photocatalyst in promoting the addition of BrCH2CN to olefins. This photocatalytic atom transfer protocol can be expanded into a wide substrate scope of aliphatic olefins bearing various functional groups, leading to the corresponding products in good to excellent yields. In addition, linchpin catalysis was developed, since the bromo group can undergo further
报道了烯烃的有效光催化的溴氰基甲基化。在一系列有机催化剂和金属络合物中,Ir(ppy)3被证明是促进向烯烃中添加BrCH 2 CN的最佳光催化剂。可以将这种光催化原子转移方案扩展到带有各种官能团的脂肪族烯烃的广泛底物范围,从而以高至极好的收率得到相应的产物。另外,由于溴基团可以进一步转化成有用的官能团,例如氨基酸的合成,因此开发了linchpin催化。
