Palladium-catalyzed aerobic oxidative cross-couplings of indoles and benzene have been achieved by using 4,5-diazafluorene derivatives as ancillary ligands. Proper choice of the neutral and anionic ligands enables control over the reaction regioselectivity.
已成功实现以钯为催化剂的吲哚和苯的好氧氧化交叉偶联反应,使用4,5-二氮芴衍生物作为辅助配体。合理选择中性和阴离子配体可以控制反应的区域选择性。
