  摘要：

  带有（R，R）-1,2-二氨基环己烷为骨架和两个对位异构体联芳基单元的C 2对称螯合二亚磷酰胺配体的手性1,5-环辛二烯铑（I）阳离子配合物，易于合成，并通过多核单核键被充分表征以及二维NMR光谱和元素分析。这些络合物在衣康酸二甲酯，2-乙酰氨基丙烯酸甲酯和（Z）-甲基-2-乙酰氨基-3-苯基丙烯酸的不对称氢化反应中用作催化剂。衍生自含两个（R）或（S）BINOL（2,2'-dihydroxy-1,1'-binaphthyl）单元被证明是有效的催化剂，具有完全的转化率和非常好的对映选择性（高达88％ee）。在Rh络合物与含两个（S）-联萘酚部分的二磷酰胺基配体催化的衣康酸二甲酯加氢中，观察到对映选择性具有不常见的正H 2压力效应。版权所有©2014 John Wiley＆Sons，Ltd.

  摘要：

  New bidentate amino-phosphoroamidite and diphosphoroamidite ligands derived from inexpensive (R,R)-1,2-diaminocyclohexane have been synthesized and screened in the Cu-catalyzed asymmetric conjugate addition of Et2Zn to 2-cyclohexenone.

  Chiral cyclopentadienyl ruthenium(II) complexes [CpRu(L1-L3)Cl] (5-7) have been prepared by reaction of (CpRu(PPh3)(2)Cl] with chiral P,P-ligands (1R,2R)-1,2-bis(diphenylphosphinamino)cyclohexane (L1), N,N'-[bis-(3,3'-bis-tert-butyl-5,5'-bis-methoxy-1,1'-biphenyl-2,2'-diyl)phosphite]-(1R,2R)-1,2-diaminocyclohexane (L2) and N,N'-[bis-(R)-1,1'-binaphtyl-2,2'-diyl)phosphite]-(1R,2R)-1,2-diaminocyclohexane (L3). The molecular structures of 5 and 6 have been determined by single-crystal X-ray analysis. Studies on catalytic activity of the cations derived from (5-7) by treatment with AgSbF6, are also reported.

• Chiral rhodium complexes containing bidentate ligands derived from (R,R)-1,2-diaminocyclohexane for catalytic enantioselective hydrosilylation of acetophenone

  日期：2004.11

  Bidentate P,P- and N,P-ligands derived from inexpensive and commercially available chiral source (R,R)-1,2-diaminocyclohexane, have been tested in the asymmetric Rh-catalyzed addition of diphenylsilane to acetophenone. Studies on the reactivity of these ligands towards the rhodium precursor [Rh(cod)Cl](2) (cod = cycloocta-1,5-diene) have shown that either monomeric, or dinuclear complexes, or both can be found in the solution. The structure of the cationic complex [Rh(cod)(3a)]PF6 (12), has been elucidated by X-ray analysis. The presence in the reaction mixture of different rhodium complexes which act as precatalysts, influences the activity and stereoselectivity of the process. (C) 2004 Elsevier B.V. All rights reserved.
