The corresponding protioligands (RPdmBox)H (R = iPr: 5a; Ph: 5b) were obtained by condensation with amino alcohols and subsequent zinc-catalyzed cyclization. Reaction of the lithiated ligands with [NiCl2(dme)] yielded the corresponding square-planar nickel(II) complexes [(RPdmBox)NiCl] (6a/b). Salt metathesis of 6a with the corresponding alkali or cesium salts in acetone led to the formation of air-
一类新的手性的C ^ 2 -对称N-供钳配体,2,5-双(2- oxazolinyldimethylmethyl)吡咯(PdmBox)H,合成从容易获得的2,2-二甲基-3-氧代丁酸乙酯开始(1)。配体骨架的合成是通过氧化烯与CuCl 2偶联,然后是Paal–Knorr型吡咯合成而实现的。通过与氨基醇缩合并随后进行锌催化的环化反应获得相应的配体配体(R PdmBox)H(R = i Pr:5a ; Ph:5b)。锂化的配体与[NiCl 2(dme)]的反应产生相应的方形镍(II)络合物[(R PdmBox)NiCl](6a / b)。丙酮中相应的碱金属盐或铯盐与6a的盐易位导致形成空气和水分稳定的[(i Pr PdmBox)NiX](X = F(7),X = Br(8),X = I (9),X = N 3(10),X = OAc(11)。此外,[[ i Pr PdmBox)NiF](7)与诸如PhSiH
