tylene, DPE = 1,2-bis(diphenylphosphino)ethylene, 4,4-byp = 4,4′-bipyridine, and t-ype = trans 1,2-bis(4-pyridyl)ethylene)]. The catalytic activities of the new complexes have been investigated in the coupling of arylboronic acid derivatives to various olefins. Results obtained showed interesting catalytic activities and chemoselectivities for the new complexes in the coupling reactions to produce
已经合成并成功表征了一系列基于螯合二亚胺和桥接二膦或二亚胺配体的新型双核Pd(II)配合物。新络合物的公式为[Pd 2(mbyp)2(DPA)2 ] [PF 6)4(1),[Pd 2(mbyp)2(DPE)2 ](PF 6)4(2),[ Pd 2(mbyp)2(4,4-byp)2 ](PF 6)4(3),[Pd 2(mbyp)2(t-pye)2 ](PF 6)4(4)[mbyp = 4,4'-二甲基-2,2'-联吡啶,DPA = 1,2-双(二苯基膦基)乙炔,DPE = 1,2-双(二苯基膦基)乙烯,4,4-byp = 4,4'-联吡啶,t-ype =反式1,2-双(4-吡啶基)乙烯)]。在芳基硼酸衍生物与各种烯烃的偶联中,已经研究了新络合物的催化活性。获得的结果表明,在游离碱或氧化剂条件下,新配合物在偶联反应中产生有趣的催化活性和化学选择性,以产生共轭加成和heck偶联产物。
