    摘要:
    Optically active rhodium catalysts with double stereoselection were prepared from the optically active chelating phosphanes Diop and Norphos and eta-1,5-cyclooctadiene rhodium complexes which contain the anions of optically active 1,3-diketones and 1,3-ketoimines based on camphor. Use of these complexes in the homogeneous enantioselective hydrogenation of (Z)-alpha-N-acetamidocinnamic acid to N-acetylphenylalanine gave optical inductions up to 90.7% and 92.3% ee for Diop and Norphos complexes, respectively. These results exceed those obtained with the corresponding phosphane-rhodium systems without additional optically active coligands.

    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。

    日期:1999.4
    The optically active complex [(-)-diop]Rh(mu(2)-H)(2)WCp2}PF6 was prepared and characterized. In four different models of enantioselective catalysis the complex gave the same enantioselectivity as the catalysts [Rh(cod)Cl](2)/(-)-diop and [Rh(cod)Cl](2)/(-)-diop/Cp2WH2.
