  • Copper- and Nickel-Catalyzed Cross-Coupling Reaction of Monofluoroalkenes with Tertiary, Secondary, and Primary Alkyl and Aryl Grignard Reagents
    作者:Hongyan Shi、Wenpeng Dai、Biyun Wang、Song Cao
    DOI:10.1021/acs.organomet.7b00859
    日期:2018.2.12
    with tertiary, secondary, and primary alkyl and aryl Grignard reagents in the presence of a catalytic amount of copper or nickel catalyst, respectively, has been developed. The reactions proceeded smoothly at room temperature, providing (E)-alkene isomers in moderate to high yields. Plausible mechanisms of the Ni-catalyzed coupling reaction of monofluoroalkene with Grignard reagents are suggested.

  • Radical-Cation Vinylcyclopropane Rearrangements by TiO<sub>2</sub> Photocatalysis
    作者:Naoya Maeta、Hidehiro Kamiya、Yohei Okada
    DOI:10.1021/acs.joc.0c00544
    日期:2020.5.15
    Radical cation vinylcyclopropane rearrangements by TiO2 photocatalysis in lithium perchlorate/nitromethane solution are described. The reactions are triggered by oxidative single electron transfer, which is followed by immediate ring-opening of the cyclopropanes to generate distonic radical cations as unique reactive intermediates. This approach can also be applied to vinylcyclobutane, leading to the
    描述了在高氯酸锂/硝基甲烷溶液中通过TiO2光催化进行的自由基阳离子乙烯基环丙烷重排。该反应由氧化性单电子转移触发,然后环丙烷立即开环以生成作为唯一反应性中间体的二甲苯基阳离子。这种方法也可以应用于乙烯基环丁烷,从而构建六元环。在初步机理研究的基础上,提出了通过二阶自由基阳离子的逐步机理,并得到密度泛函理论计算的支持。
  • The action of sodium hydrogen telluride on olefins
    作者:Derek H.R. Barton、Luis Bohé、Xavier Lusinchi
    DOI:10.1016/s0040-4020(01)87834-0
    日期:1990.1
    action of sodium hydrogen telluride, NaTeH, on non electrophilic carbon-arbon double bonds has been investigated.The reaction is found to be very sensitive to the substituents on the ethylenic linkage. Whereas phenyl conjugated olefins are reduced to alkylbenzenes,the reagent adds to isolated mono and disubstituted double bonds leading to organotellurium derivatives and with gem-disubstituted ones it leads

  • A Highly Reduced Ni–Li–Olefin Complex for Catalytic Kumada–Corriu Cross-Couplings
    作者:Lukas Nattmann、Sigrid Lutz、Pascal Ortsack、Richard Goddard、Josep Cornella
    DOI:10.1021/jacs.8b09849
    日期:2018.10.24
    The catalytic activity of a highly reduced Ni catalyst in the context of a Kumada-Corriu cross coupling has been studied. This nickel complex is characterized by its high electron density, stabilized by simple olefin ligands in combination with two Li ions. Landmark reactivity has been found with this precatalyst which operates at cryogenic temperatures, thus allowing the presence of sensitive functionalities. Structural elucidation of oxidative addition intermediates and their reactivity suggest highly reduced species being operative in the C-C bond forming event.
  • Mechanism of the Ni(0)-Catalyzed Vinylcyclopropane−Cyclopentene Rearrangement
    作者:Selina C. Wang、Dawn M. Troast、Martin Conda-Sheridan、Gang Zuo、Donna LaGarde、Janis Louie、Dean J. Tantillo
    DOI:10.1021/jo901525u
    日期:2009.10.16
    A combination of physical organic experiments and quantum chemical calculations were used to construct a detailed mechanistic model for the Ni(0)-N-heterocyclic carbene-catalyzed vinylcyclo-propane-cyclopentene rearrangement that involves a mutistep oxidative addition/haptotropic shift/reductive elimination pathway. No evidence for the intermediacy of radicals or zwitterions was found. The roles of substituents on the vinylcyclopropane substrate and variations in the ligands on Ni were evaluated. It is postulated that bulky carbene ligands facilitate formation of the active catalyst species.
