    卤化物的添加到该类型的阳离子溶剂化物复合物的[Rh(PP)(溶剂)2 ] [阴离子]导致三核的形成μ 3 -卤化物桥连的络合物。相应的配合物的[Rh 3(PP)3(μ 3 -X)2 ] [BF 4 ]其中X = Cl或Br和二膦PP ME-DUPHOS ET-DUPHOS,DIPAMP,吨-Bu-BISP *和Tangphos分别在大多数情况下,其特征还在于X射线分析。通过降低活性催化剂的浓度,原位形成这些μ卤化物桥连的多核络合物在催化反应中导致活性降低,甚至导致总活性降低。所需的卤化物(大多数情况下为氯化物)通常以杂质形式存在于基材中(工业生产时也是如此)。从酶催化中被称为竞争抑制的失活程度取决于几个因素:卤化物的类型,多核卤化物配合物和底物配合物的稳定常数之比,以及溶液中卤化物和底物的浓度。

    The addition of halides to the cationic solvate complexes of the type [Rh(PP)(solvent)2][anion] leads to the formation of trinuclear μ3-halide-bridged complexes. The corresponding complexes [Rh3(PP)3(μ3-X)2][BF4] with X = Cl or Br and diphosphines PP Me-DuPHOS, Et-DuPHOS, DIPAMP, t-Bu-BisP* and Tangphos were characterized – in most cases – also by X-ray analysis.
