  route to homoleptic complex [Pt(CAACMe)2] (CAAC=cyclic (alkyl)(amino)carbenes) and convenient routes to new heteroleptic complexes of the form [Pt(CAACMe)(PR3)] are presented. Although the homoleptic complex was found to be inert to many reagents, oxidative addition and metal‐only Lewis pair (MOLP) formation was observed from one of the heteroleptic complexes. The spectroscopic, structural, and electrochemical

  提出了一种改进的合成方法，制备了均相复合物[Pt（CAAC Me）2 ]（CAAC =环（烷基）（氨基）碳烯），并便捷地合成了新的[Pt（CAAC Me）（PR 3）形式的杂合复合物。。尽管发现同型配合物对许多试剂均呈惰性，但从其中一种杂合剂配合物中观察到了氧化加成反应和仅金属路易斯对（MOLP）的形成。与密度泛函理论（DFT）和时变密度泛函理论（TD-DFT）计算一起探索了零价配合物的光谱，结构和电化学性质。同功[Pt（CAAC）2 ]和同功[Pt（CAAC）（PR 3）]发现配合物的光谱和结构性质相似，但它们的电化学行为和反应性差异很大。通过TD-DFT计算研究了含CAAC的Pt 0配合物异常强的颜色，这归因于配合物的LUMO激发，其主要由Pt和CAAC碳原子之间的键π相互作用组成。

Reactions with relatively nonbulky platinum(0) complexes led to the formation of unsymmetrical cis-bis(boryl) complexes cis-[(R3P)2Pt(BF2)(BMes2)] (6, R = Me; 7, R = Et) as well as the first example of a fourfold-unsymmetrical bis(boryl) complex, [(Me3P)(Cy3P)Pt(BF2)(BMes2)] (12). The use of a more bulky Pt complex provided access to the

  6-tetramethylphenyl) groups. Halide abstraction from the 4-tert-butylphenyl complex resulted in a T-shaped cationic boryl complex. However, subjecting the duryl-substituted complexes to the same conditions exclusively results in terminal cationic borylene complexes, a difference we attribute to the greater steric hindrance between the boron-bound bromide and the methyl groups at the 2- and 6-positions of the

  以前已显示从Pt II二膦硼烷基络合物中提取卤代配体可产生两种异构产物之一：T形阳离子硼基络合物或方平面阳离子硼基络合物。然而，仅在一种情况下观察到后一种产物，即间苯二甲酰基配体的产物，其在卤代夺去时转化为间苯二甲烯基配体。为了在不同的空间和电子影响下测试该反应的效力，制备了具有4-叔丁基苯基和duryl（2,3,5,6-四甲基苯基）基团的Pt II二膦硼烷基配合物。从4叔抽象卤化物丁基苯基络合物产生T形阳离子硼基络合物。但是，将duryl取代的配合物置于相同条件下只会导致末端阳离子亚芳基配合物，我们的差异归因于结合硼的溴化物与duryl的2位和6位甲基之间的较大位阻团体。该结果表明在对位的烷基化的电子效应不是该亚芳基形成反应的因素。

  The reaction of Pt(PiPr(3))(3) with SO2 led to the formation of (PiPr(3))(2)Pt(SO2) (1), isolated in 93% yield. The addition of [H(OEt(2))(2)](BArf)-B-+(BArf = B(3,5-(CF3)(2)C6H3)(4)) to 1 in ether at -78 degrees C afforded the solvent complex trans-[(PiPr(3))(2)Pt(H)(OEt(2))]BArf (2) in 85% isolated yield. Complex 2 served as a precursor to monodentate halocarbon complexes of the type Pt(eta(1)-XR). The dichloromethane complex trans-[(PiPr(3))(2)Pt(H)(eta(1)-ClCH2Cl)]BArf (3) was isolated in 80% yield by the recrystallization of 2 from CH2Cl2/hexane. IR spectroscopy suggested the existence of dichloromethane binding which was confirmed by X-ray crystallography. The reaction of 2 or 3 with iodo- or bromobenzene led to the isolation of the haloarene complexes trans-[(PiPr(3))(2)Pt(H)(eta(1)-XPh)]BArf, where X = I (4, 87% yield) or Br (5, 60% yield). Both compounds were characterized spectroscopically and by X-ray crystallography. An unexpected steric interaction in 4, suggested by molecular mechanics calculations to be significant, was rationalized in terms of halide-to-metal pi bonding. The PhI complex 4 decomposed under harsh conditions to the bridging iodide compound trans-[(PiPr(3))(2)Pt(H)](2)(mu-I)}BArf (6) which was structurally characterized. The THF adduct [(PiPr(3))(2)Pt(H)(THF)]BArf (7), isolated in 78% yield and also characterized by X-ray crystallography, was formed when any of the compounds 2, 3, 4, or 5 was dissolved in THF. The CH2Cl2 complex 3 reacted with H-2 to form the dihydrogen complex tans-[(PiPr(3))(2)Pt(H)(eta(2)-H-2)]BArf which was characterized by NMR spectroscopy.
