The reaction of RhCl3·3H2O with (EEE)-1,5,9-cyclododecatriene in alcohols gives a red polymeric solid compound with chlorine bridges, 1, in which the hydrocarbon moiety has been reported to be bonded to the metal via an η3-allylic bond. Re-examination of this reaction has led to the isolation of soluble derivatives obtained by breaking the chlorine bridges with chelating diphosphines and diamines.
RhCl 3 ·3H 2 O与(EEE)-1,5,9-环十二碳三烯在醇中的反应生成带有氯桥1的红色聚合固体化合物,据报道其中的烃部分通过的η 3 -烯丙基键。该反应的重新检查导致分离出可溶的衍生物,该可溶的衍生物是通过用螯合的二膦和二胺破坏氯桥而获得的。对二膦基和二氨基衍生物的单晶进行X射线分析表明,组成为C 12 H 17的环烯烃残基已经经历了异构化。与金属键合不涉及的两个双键是5,8而不是5,9。
