  二苯基膦基或二环己基膦酸酯系的硼基钳形配体：PBP铱（III）配合物的合成及其向铱-乙烯配合物的转化

  摘要：

  合成了两个在磷原子上带有苯基或环己基的PBP钳位配体的氢硼烷前体（1b，c），并研究了它们与铱的络合反应。带有苯基的氢硼烷1b与Ir [P（p- tol）3 ] 2（CO）Cl反应，得到18电子配合物[PhPBP] Ir（H）（CO）Cl（3b），但与其他铱（I）源产生复杂的混合物。与先前报道的t Bu-PBP衍生物3a相比，3b中的特征IR峰在理论计算的基础上进行了讨论。环己基取代的氢硼烷1c与[Ir（C 2 H 4）2 Cl] 2的络合得到16电子络合物[CyPBP] Ir（H）Cl（2c）。X射线结构和对2c的计算研究表明，氢化物配体与硼原子接近[B = 1.90（5）Å]。的反应2C乙烯气氛下LiTMP（TMP = 2,2,6,6- tetramethylpipyridide）得到的一价铱络合物[CyPBP]铱（C 2 H ^ 4）（图4c）通过类似的过程与先前报道的[吨BuPBP

  N-Heterocyclic Silyl Pincer Ligands

  摘要：

  The reaction of 1,2-C6H4(NHCH2PPh2)(2) with chlorosilanes Cl2SiHR (R = Ph, Cl) affords the benzosiladiazoles RHSi(NCH2PPh2)(2)C6H4 (R = Ph, 1; Cl, 2). The phenyl derivative 1 undergoes chelate-assisted Si H activation with [RuPhCl(CO)(PPh3)(2)] and [RhCl(PPh3)(3)] to afford the structurally characterized silyl pincer complexes [RuCl(CO)(PPh3){kappa(3)-P,Si,P'-SiPh(NCH2PPh2)(2)C6H4}] (3) and [RhHCl(PPh3){kappa(3)-P,Si,P'-SiPh(NCH2PPh2)(2)C6H4}] (4). The reaction of 4 with [Et2NH2][S2CNEt2] affords the complex [RhH(S2CNEt2){kappa(3)-P,Si,P'-SiPh(NCH2PPh2)(2)C6H4}] (5), structural data for which demonstrate a pronounced trans influence for the alpha-silyl donor.

  Pincer complexes are widely used in organometallic and coordination chemistry. The role of antimony as a central donor atom in pincer ligands has been extensively explored in recent years. Although phenylenediamine derived PXP (X = B, Al, C, Si, Ge, Sn, N) type ligands exhibit diverse reactivity, analogues species based on antimony have been reported less frequently. Herein, we report a new PSbP complex

  Pincer配合物广泛用于有机金属和配位化学。近年来，锑在钳位配体中作为中心供体原子的作用已得到广泛研究。尽管苯二胺衍生的PXP（X = B，Al，C，Si，Ge，Sn，N）型配体表现出不同的反应性，但基于锑的类似物物种的报道却很少。在此，我们报告了一种新的PSbP复合物并评估了其反应性。这些物种将拓宽苯二胺衍生的钳形复合物家族。

  pnictogen ligands, such as nitrenium and phosphenium, has been well-explored in recent years. However, corresponding studies of a heavier congener, stibenium ion, are rare. To better facilitate a Sb+–metal interaction, a tridentate P-Sb+-P ligand with two phosphine buttresses was designed and synthesized, and its coordination chemistry toward late transition metals was investigated. The stibenium ligand

• Synthesis and Reactivity of N-Heterocyclic PSiP Pincer Iron and Cobalt Complexes and Catalytic Application of Cobalt Hydride in Kumada Coupling Reactions

  The new N-heterocyclic sigma-silyl pincer ligand HSiMe-(NCH2PPh2)(2)C6H4 (1) was designed. A series of tridentate silyl pincer Fe and Co complexes were prepared. Most of them were formed by chelate-assisted Si-H activation. The typical iron hydrido complex FeH(PMe3)(2)(SiMe(NCH2PPh2)(2)C6H4) (2) was obtained by Si-H activation of compound 1 with Fe(PMe3)(4). The combination of compound 1 with CoMe(PMe3)(4) afforded the Co(I) complex Co(PMe3)(2)(SiMe(NCH2PPh2)(2)C6H4) (3). The Co(III) complex CoHCl(PMe3)(SiMe(NCH2PPh2)(2)C6H4) (5) was generated by the reaction of complex 1 with CoCl(PMe3)(3) or the combination of complex 3 with HCl. However, when complex 3 was treated with MeI, the Co(II) complex CoI(PMe3)(SiMe(NCH2PPh2)(2)C6H4) (4), rather than the Co(III) complex, was isolated. The catalytic performance of complex 5 for Kumada coupling reactions was explored. With a catalyst loading of 5 mol %, complex 5 displayed efficient catalytic activity for Kumada cross-coupling reactions of aryl chlorides and aryl bromides with Grignard reagents. This catalytic reaction mechanism is proposed and partially experimentally verified.
