    摘要:
    The reaction between Ni(O) complexes (dp) (dp = 1,2-bis(dicyclohexylphosphino)ethane, 1,3-bis(dicyclohexylphosphino) propane, 1,4-bis(dicyclohexylphosphino)butane; dcpe, dcpp, dcpb, respectively) and carbon dioxide is described. The influence of the P-Ni-P bond angle on the stability of the corresponding adducts is discussed. The reactions of Ni(dcpp)CO2 and Ni(dcpb)CO2 with dioxygen are also described.

    and kinetically competent catalysts for this transformation. The fleeting transmetalation intermediate has been successfully synthesized through an alternative synthetic organometallic pathway at lower temperature, allowing for in situ NMR study of the C–N bond reductive elimination step. This study addresses key factors governing the mechanism of the nickel-catalyzed Buchwald–Hartwig amination process
    在本文中,我们报道了1,2,2-双(二环己基膦基)乙烷(dcype)配合物用于芳基醚的Buchwald-Hartwig催化胺化。该方案显示了在催化条件下可耐受的各种不同官能团的广泛适用性。广泛的有机属和动力学研究支持这种转化的(0)-(II)途径,并揭示了氧化加成配合物是催化循环的静止状态。已证明所有分离出的中间体都是这种转化的催化和动力学催化剂。通过在较低的温度下通过另一种合成的有机属途径,已经成功合成了短暂的重属化中间体,从而可以对C–N键的还原消除步骤进行原位NMR研究。

    Aryne–nickel complexes [Ni(η 2 -C 6 H 4 )L 2 ] [L 2 = 2PEt 3 or dcpe; dcpe = (C 6 H 11 ) 2 PCH 2 CH 2 P(C 6 H 11 ) 2 ] and [Ni(η 2 -C 10 H 6 )(PEt 3 ) 2 ] reacted readily with C 2 F 4 to form the corresponding five-membered tetrafluoro-substituted nickelacycles [Ni(C 6 H 4 CF 2 CF 2 -2)L 2 ] (L 2 = dcpe or 2PEt 3 ) and [Ni(2-C 10 H 6 CF 2 CF 2 -3)(PEt 3 ) 2 ], respectively. The complex [Ni(C 6 H 4 CF 2 CF 2 -2)(dcpe)] is very stable towards air, whereas the PEt 3 analogues react readily to give µ-aryloxo dimers. The naphthalene-based dimer [Ni(µ-2-OC 10 H 6 CF 2 CF 2 -3)(PEt 3 )} 2 ] has been structurally characterized. The complexes [Ni(C 6 H 4 CF 2 CF 2 -2)L 2 ] insert CO into their aryl–nickel bonds to form six-membered acyl complexes [NiC(O)C 6 H 4 CF 2 C F 2 -2}L 2 ] (L 2 = dcpe or 2PEt 3 ) and, after CO-induced reductive elimination, 2,2,3,3-tetrafluoroindanone. The dcpe acyl complex has also been shown to undergo reaction with air to form the carboxylato complex [NiOC(O)C 6 H 4 CF 2 C F 2 -2}(dcpe)], whose structure has been confirmed by X-ray crystallography. Some insertions of acetylenes into the aryl–nickel bonds of [Ni(C 6 H 4 CF 2 CF 2 -2)L 2 ] are also reported.
    Aryne–配合物 [Ni(η²-C6H4)L2] [L2 = 2PEt3或dcpe;dcpe = (C6H11)2PCH2CH2P( )2] 和 [Ni(η²-C10H6)(PEt3)2] 很容易与C2F4反应,形成相应的五元四取代环 [Ni( CF2CF2-2)L2] (L2 = dcpe或2PEt3) 和 [Ni(2- CF2CF2-3)(PEt3)2]。配合物 [Ni( CF2CF2-2)(dcpe)] 对空气非常稳定,而PEt3 的类似物则容易反应生成μ-芳氧二聚体。基于的二聚体 [Ni(μ-2-O CF2CF2-3)(PEt3)}2] 已被结构表征。配合物 [Ni( CF2CF2-2)L2] 将CO插入其芳基–键,形成六元酰基配合物 [NiC(O) CF2CF2-2}L2] (L2 = dcpe或2PEt3),并在CO诱导下进行还原消除,生成2,2,3,3-四印酮。dcpe 酰基配合物也已被证明可以与空气反应形成羧酸盐配合物 [NiOC(O) CF2CF2-2}(dcpe)],其结构已通过X射线晶体学确认。也有一些关于碳乙炔插入 [Ni( CF2CF2-2)L2] 中芳基–键的报道。

    esters with monodentate phosphines and low-valent nickel complexes still remains elusive. Herein, we report a combined experimental and theoretical study on the Ni(0)/PCy3-catalyzed silylation of aryl pivalates with CuF2/CsF additives that reveals the involvement of unorthodox dinickel oxidative addition complexes in C-O bond cleavage and their relevance in C-Si bond formation. We have obtained a mechanistic
    单齿膦配体经常用于芳基酯的催化 CO 官能化。然而,关于此类反应的大量准备工作与缺乏有关相关中间体的结构和反应性的信息形成鲜明对比。事实上,对于芳酯与单齿膦和低价配合物的 CO 键的看似微不足道的氧化加成的实验证据仍然难以捉摸。在此,我们报告了 Ni(0)/PCy3 催化的新戊酸芳基与 CuF2/CsF 添加剂的硅烷化的联合实验和理论研究,揭示了非正统二氧化加成配合物参与 CO 键断裂及其与 C-Si 的相关性键的形成。我们获得了一张机械图,阐明了添加剂的作用,并证明了二配合物通过歧化作用作为传播的单体配合物的储库。我们相信这项研究将作为一个有用的切入点,以解开使用单齿膦的其他相关催化 CO 功能化反应的机制基础。
