    Two-Electron HCl to H2 Photocycle Promoted by Ni(II) Polypyridyl Halide Complexes
    摘要:
    Photochemical HX splitting requires the management of two protons and the execution of multielectron photoreactions. Herein, we report a photoinduced two-electron reduction of a polypyridyl Ni(II) chloride complex that provides a route to H-2 evolution from HCl. The excited states of Ni complexes are too short to participate directly in HX activation, and hence, the excited state of a photoredox mediator is exploited for the activation of HX at the Ni(II) center. Nanosecond transient absorption (TA) spectroscopy has revealed that the excited state of the polypyridine results in a photoreduced radical that is capable of mediating HX activation by producing a Ni(I) center by halogen-atom abstraction. Disproportionation of the photogenerated Ni(I) intermediate affords Ni(II) and Ni(0) complexes. The Ni(0) center is capable of reacting with HX to produce H-2 and the polypyridyl Ni(II) dichloride, closing the photocycle for H-2 generation from HCl.

    从天然硫醇中进行 C-S 活化和脱硫具有挑战性,这限制了它们在有机合成中作为原料的应用,尽管它们天然丰富。在此,我们将用作氧化还原活性支架的全氟/多氟芳基部分引入 sp 3杂化硫醇中以激活 C-S 键。使用具有 MgBr 2作为添加剂的 Ni 催化剂,可以去除 S 基团以产生可以与芳基卤化物在还原交叉偶联中反应的脂肪族自由基。

    A new C−C bond-forming reaction between alkenyl acetates and alkyl bromides was achieved by reductive nickel catalysis. This method offers very mild reaction conditions for facile and precise synthesis of structurally versatile aliphatic alkenes using readily available and stable alkenyl reagents. It allows for a gram-scale reaction and modification of biologically active molecules, and it affords

    Polypyridine-ligated nickel complexes are widely used as privileged catalysts in a variety of cross-coupling reactions. The rapid adoption of these complexes is tentatively attributed to their ability to shuttle between different oxidation states and engage in electron-transfer reactions. However, these reactions are poorly understood in mechanistic terms. Here we investigate the reactivity of pseudohalide-
    吡啶连接的配合物在各种交叉偶联反应中被广泛用作特权催化剂。这些复合物的快速采用初步归因于它们能够在不同的氧化态之间穿梭并参与电子转移反应。然而,这些反应在机械学方面知之甚少。在这里,我们研究了含有聚吡啶配体的假卤化物和卤化物连接的 Ni(II) 配合物在电子转移反应中的反应性。具体来说,Ni(II) 卤化物络合物在生成 Ni(I)Ln 物种的过程中非常容易触发与 Ni(0) 的配比,而相应的 Ni(II) 伪卤化物同系物对电子转移具有抗性,而 Ni(I) 拟卤化物容易发生歧化不配事件。这些观察结果得到了电化学技术和详细的量子力学计算的证实。我们还表明,在外生盐存在下,催化失活的 Ni(II) 伪卤化物复合物可以重新激活。从更广泛的角度来看,本研究为 Ni 催化交叉偶联领域中被忽视的基本步骤提供了合理化,从而为设计未来的 Ni 催化反应提供了蓝图。
