Enantioselective reactions of a wide variety of benzyl nitriles with N-tosylimines catalyzed by novel chiral 1,3-bis(imidazolin-2-yl)benzene-palladium(II) [Phebim-Pd(II)] complexes have afforded the respective products in high yield with good enantioselectivity. A reaction mechanism is proposed based on X-ray crystal structures of palladium complexes.
新型手性1,3-双(咪唑啉-2-基)苯钯(II)[Phebim-Pd(II)]配合物催化的各种苄腈与N-甲苯胺的对映选择性反应提供了各自的产物高收率和良好的对映选择性。基于钯配合物的X射线晶体结构,提出了一种反应机理。
