文摘
A series of geometry-constrained iminopyridyl-palladium chlorides were synthesized and characterized. These phosphine-free palladium complexes were explored for their catalytic activities in both Suzuki and Heck cross-coupling reactions, achieving turnover numbers as high as 106 towards various aryl bromides, even those containing various functionalities. In addition, the influence of substituents with steric and electronic factors was reflected by the differences observed in their activities.
