  Reaction of [Pt(C2H4)(PR3)2](R = Ph or C6H4Me-4) with moderately bulky phosphines at low temperatures did not give the expected tris- or tetrakis-phosphine complexes. Instead, mixed-phosphine complexes of the type [Pt(C2H4)(PR3)(PR′3)](R′= C6H11, C6H4OMe-4, C6H4OMe-2, C6H4Me-4 or CH2Ph) were formed. With less bulky phosphines, chelating diphosphines or phosphites, mixed tetrakis complexes, many of them prone to disproportionation, were formed. The complexes were characterised by 31P and 195Pt NMR spectroscopy in solution.

  在低温下，[Pt(C2H4)(PR3)2](R = Ph或C6H4Me-4)与中等体积的膦反应并未生成预期的三膦或四膦配合物。相反，形成了类型为[Pt( )(PR3)(PR′3)]的混合膦配合物（R′= C6H11, C6H4OMe-4, C6H4OMe-2, C6H4Me-4或CH2Ph）。与体积较小的膦反应时，形成了配位的二膦或磷酸酯的混合四膦配合物，其中许多配合物易于发生不均匀化。该配合物通过31P和195Pt NMR光谱在溶液中进行了表征。

  The electrochemical reduction of [PtCl2L2]+ L2* (L2 and L2* = Ph2PCH2CH2 PPh2, dppe; Cy2PCH2CH2PCy2, dcpe; nBu2PCH2CH2PnBu2, dbpe) systems may proceed via two different routes. Path 1 involves reduction of [PtCl2L2] to produce [PtL2] which is trapped by L2* to form [PtL2L2*]. Path 2 involves prior reaction of [PtCl2L2] with L2* to form [PtL2L2*]2+ which is reduced to form [PtL2L2*]. The extent of prior

  [PtCL2L2] + L2 *（L2和L2 * = Ph2PCH2CH2 PPh2，dppe; Cy2PCH2CH2PCy2，dcpe; nBu2PCH2CH2PnBu2，dbpe）系统的电化学还原可通过两种不同的途径进行。路径1涉及[PtCL2L2]的还原，以产生[PtL2]，其被L2 *捕获，形成[PtL2L2 *]。路径2涉及[PtCL2L2]与L2 *的先反应以形成[PtL2L2 *] 2+，然后还原为[PtL2L2 *]。[PtCL2L2]与L2 *的先验反应程度已通过循环伏安法（仅检测溶液中的电活性成分）和31P 1H} NMR光谱（可进行结构分配）进行监控。在足以降低[PtCL2L2]和[PtL2L2 *] 2+的电势下以及在足以降低[PtL2L2 *] 2+但不能降低[PtCL2L2]的电势下进行本体电解。通过31P 1H} NMR光谱进行的产品分析显示，路径1在空间
