摘 要: 通过三甲基铝活化苯胺生成铝胺盐,再与α-二酮反应制备了一系列大位阻结构的α-二亚胺配体。在与氯化钯原位作用下,大位阻取代的α-二亚胺配体用于Suzuki偶联反应,研究了配体结构对偶联反应的影响。 A series of α-diimine ligands were synthesized in high yield through the activation of primary aniline with trimethylaluminum to form aminoalanes,and following by reacting with bulky α-ketones.In the presence of PdCl2 in situ,the α-diimine ligands were applied in Suzuki cross-coupling,and the relationship between ligand structure and catalytic activity was investigated.
