Three benzenedicarboxamide ligands (L) were designed and synthesized, and each was used to prepare a palladium(II) complex Pd(L)Br and Pd(L)(OAc). These NCN pincer complexes were used to catalyze the α-arylations of a variety of ketones with aryl chlorides or bromides in various solvents, and moderate-to-excellent yields were obtained (up to 95%). Further research showed that unactivated and sterically
设计并合成了三种苯二甲酰胺配体(L),并分别用于制备钯(II)配合物Pd(L)Br和Pd(L)(OAc)。这些NCN钳形配合物用于在各种溶剂中催化各种酮与芳基氯化物或溴化物的α-芳基化反应,获得了中等至优异的产率(高达95%)。进一步的研究表明,未活化和空间位阻的芳基卤化物和酮也是合成α-芳基化的合适底物。
