  Amidinato- and triazenido-bridged binuclear complexes of palladium and platinum

  摘要：

  The reaction of [M2Cl2(mu-Cl)(2)(PR3)(2)] (M=Pd or Pt; PR3=PEt3, PBu3, PMe2Ph, PMePh2) with lithium amidinate or sodium triazenide gave binuclear complexes containing amidinato- or triazenido-bridges, [M2Cl2(mu-ArNENAr)(2)(PR3)(2)] (E=CH, CMe or N). These complexes were characterized by elemental analysis and NMR (H-1, P-31 or Pt-195) data. The structures of two complexes, [(PdCl2)-Cl-2(mu-PhNC(Me)NPh)(2)(PMe2Ph)(2)] (10) and [Pt2Cl2(mu-PhNNNPh)(2)(PEt3)(2)] (11) were established by single crystal X-ray structural analyses. The Pt-195 NMR data Show coupling between two metal centers in the cis triazenido-bridged complex. The corresponding amidinate bridged complex does not show coupling. The role of the bridging ligand in mediating interaction between the metal centers is probed through Extended Huckel Theory (EHT) calculations. It is suggested that M-M interactions are primarily affected by the bridging ligands. (C) 1998 Elsevier Science Ltd. All rights reserved.

  The reactions of [M₂Cl₂(μ-Cl)₂(PR₃)₂] with acetamidines in 1:2 stoichiometry afforded mononuclear complexes, [MCl₂ArNHC(Me)NAr}(PR₃)] (I) (M = Pd or Pt; R₃ = Et₃, Bu₃, Me₂Ph, MePh₂; Ar = Ph or 4-MeC₆H₄ (tol)). Treatment of [M₂Cl₄(PR₃)₂] with Li[ArNC(Me)NAr] under anerobic conditions gave acetamidino-bridged binuclear complexes, [M₂Cl₂(μ-ArNC(Me)NAr)₂(PR₃)₂] (II). The reaction of [Pd₂(μ-Cl)₂(η³-allyl)₂] with Ag[ArNC(Me)NAr] gave acetamidino-bridged allyl complexes [Pd₂(μ-ArNC(Me)NAr)₂(η³-allyl)₂] (III). All the complexes were characterized by elemental analyses and NMR (¹H, ³¹P, ¹⁹⁵Pt) spectroscopy. The mononuclear complexes (I) exist in two isomeric forms differing in the coordination of monodentate acetamidine ligand. The ³¹P and ¹⁹⁵Pt NMR data on binuclear complexes (II) indicate that there is no significant Pt–Pt interaction. The allyl complexes (III) (allyl = C₃H₅) exhibit formation of all three possible isomers, whereas methallyl (allyl = C₄H₇) derivatives exist only in one configuration. Key words: palladium, platinum, acetamidine, NMR (¹H, ³¹P, ¹⁹⁵Pt), mononuclear complexes, binuclear complexes.

  [M₂Cl₂(μ-Cl)₂(PR₃)₂]与乙酰胺在1：2的化学计量比下反应，生成单核配合物，[MCl₂ArNHC(Me)NAr}(PR₃)] (I) (M = Pd或Pt；R₃ = Et₃，Bu₃，Me₂Ph，MePh₂；Ar = Ph或4-MeC₆H₄ (tol))。将[M₂Cl₄(PR₃)₂]与Li[ArNC(Me)NAr]在无氧条件下反应，得到乙酰胺桥联的双核配合物，[M₂Cl₂(μ-ArNC(Me)NAr)₂(PR₃)₂] (II)。[Pd₂(μ-Cl)₂(η³-allyl)₂]与Ag[ArNC(Me)NAr]反应，生成乙酰胺桥联的烯丙基配合物，[Pd₂(μ-ArNC(Me)NAr)₂(η³-allyl)₂] (III)。所有配合物均通过元素分析和NMR (¹H，³¹P，¹⁹⁵Pt)光谱表征。单核配合物(I)存在两种异构形式，其区别在于单齿乙酰胺配体的配位方式。双核配合物(II)的³¹P和¹⁹⁵Pt NMR数据表明不存在显著的Pt-Pt相互作用。烯丙基配合物(III) (烯丙基 = C₃H₅) 显示出所有三种可能的异构体形成，而甲基烯丙基 (烯丙基 = C₄H₇) 衍生物只存在一种构型。关键词：钯、铂、乙酰胺、NMR (¹H，³¹P，¹⁹⁵Pt)、单核配合物、双核配合物。
