  • Paired Oxidative and Reductive Catalysis: Breaking the Potential Barrier of Electrochemical C(sp<sup>3</sup>)−H Alkenylation**
    作者:Long Zou、Xiaofan Wang、Siqi Xiang、Weipeng Zheng、Qingquan Lu

    Abstract

    Due to the intrinsic inertness of alkanes, strong oxidative conditions are typically required to enable their C(sp3)−H functionalization. Herein, a paired electrocatalysis strategy was developed by integrating oxidative catalysis with reductive catalysis in one cell without interference, in which earth‐abundant iron and nickel are employed as the anodic and cathodic catalysts, respectively. This approach lowers the previously high oxidation potential required for alkane activation, enabling electrochemical alkane functionalization at the ultra‐low oxidation potential of ≈0.25 V vs. Ag/AgCl under mild conditions. Structurally diverse alkenes, including challenging all‐carbon tetrasubstituted olefins, can be accessed using readily available alkenyl electrophiles.

    摘要由于烷烃的内在惰性,通常需要在强氧化条件下才能实现其 C(sp3)-H 功能化。在此,我们开发了一种成对电催化策略,将氧化催化与还原催化无干扰地集成在一个电池中,其中采用了富含地球的铁和镍分别作为阳极和阴极催化剂。这种方法降低了以往烷烃活化所需的高氧化电位,在温和的条件下,以相对于 Ag/AgCl ≈0.25 V 的超低氧化电位实现了电化学烷烃官能化。利用容易获得的烯基亲电体,可以获得结构多样的烯烃,包括具有挑战性的全碳四取代烯烃。
  • Unactivated C(sp<sup>3</sup>)–H Bond Functionalization of Alkyl Nitriles with Vinylarenes and Mechanistic Studies

    The first example of a metal-free unactivated C(sp(3))-H bond functionalization of alkyl nitriles with terminal vinylarenes to provide gamma-ketonitrile derivatives is described. This protocol features simple operations, a broad substrate scope, and atom and step economy. In addition, Cu-catalyzed C(sp(3))-H bond functionalization of azodi-isobutyronitrile (AIBN) and analogues with terminal vinylarenes to generate gamma-ketonitriles was also studied. A preliminary free-radical pathway was confirmed by capturing an alkyl radical, and a conjugate system was found that can stabilize radical intermediates and be in favor of this transformation. Density functional theory (DFT) calculations also provide important evidence of the free-radical pathway.

    Various β-nitro ketones, including those bearing a β-tertiary carbon, were prepared from geminal bromonitroalkanes and trimethylsilyl enol ethers of a broad range of ketones by visible light photoredox catalysis, which were then easily converted into β-amino ketones, 1,3-amino alcohols, α,β-unsaturated ketones, β-cyano ketones and γ-nitro ketones.

    A new and efficient oxidative coupling reaction between enoxysilane and alkylnitrile radicals derived from readily available AIBN and its analogues has been developed by using redox-active metal as a catalyst in which the redox-active copper is used for enhancing the electrophilicity of a free radical via coordination and bringing the radical and nucleophilic enol ether closer to facilitate the single-electron
