    Difluoromethyl radicals bearing ester, phosphonate, nitrile, cyclic carbonate, and carbamate groups were generated by the photoinitiated S–CF2 bond cleavage of electrosynthesized α,α-difluorosulfides, and their addition to olefins and aromatic substitution were successfully carried out to provide the regioselective adducts and substitution products in moderate yields.

  • Design Principles for Trap-Free CsPbX<sub>3</sub> Nanocrystals: Enumerating and Eliminating Surface Halide Vacancies with Softer Lewis Bases

    We introduce a general surface passivation mechanism for cesium lead halide perovskite materials (CsPbX3, X = Cl, Br, I) that is supported by a combined experimental and theoretical study of the nanocrystal surface chemistry. A variety of spectroscopic methods are employed together with ab initio calculations to identify surface halide vacancies as the predominant source of charge trapping. The number
    我们介绍了铯铅卤化物钙钛矿材料(CsPbX3,X = Cl,Br,I)的一般表面钝化机制,该机制得到了纳米晶体表面化学的联合实验和理论研究的支持。各种光谱方法与 ab initio 计算一起使用,以识别表面卤化物空位作为电荷俘获的主要来源。每个纳米晶体的表面陷阱数量通过 1H NMR 光谱量化,该数量与简单的陷阱模型一致,其中表面卤化物空位产生有害的欠配位铅原子。这些卤化物空位表现出在 CsPbCl3、CsPbBr3 和 CsPbI3 之间不同的捕获行为。从头计算表明,引入阴离子 X 型配体可以通过改变基于铅的缺陷水平的能量学来产生无陷阱带隙。通过考虑配位化学的既定原理,介绍了选择有效钝化配体对的一般规则。引入更软的、阴离子的、X 型路易斯碱,以配位不足的铅原子为目标,导致绝对量子产率接近统一和单指数发光衰减动力学,从而表明完全陷阱钝化。这项工作为制备具有可变成分和尺寸的高发光 CsPbX3
  • Nickel-catalyzed reaction of iododifluoroacetates with alkenes and zinc: a novel and practical route to .alpha.,.alpha.-difluoro-functionalized esters and .alpha.,.alpha.,.omega.,.omega.-tetrafluoro diesters
    作者:Zhen Yu Yang、Donald J. Burton
    DOI:10.1021/jo00045a027
    日期:1992.9
    lododifluoroacetates 1a-c react with alkenes and zinc in the presence of nickel dichloride hexahydrate in THF at room temperature or 60-degrees-C to give the corresponding alpha,alpha-difluoro esters in good yields. The reaction is also applicable to alkenes containing a variety of functional groups such as trimethylsilyl, hydroxy, ketone, and ester moieties. The reaction of 1 works well with dienes; the products formed depend on the length of chain of the dienes. 1,8-Nonadiene and 1,5-hexadiene afford the alpha,alpha,omega,omega-tetrafluoro diesters, while 1,6-heptadiene gave a mixture of ethyl 2,2-difluoro-8-nonenoate (19) and the cyclopentyl-substituted alpha,alpha-difluoro ester 20. When diallyl ether was used as a substrate, only the tetrahydrofuran derivative 21 was formed. The nickel-catalyzed reaction can be suppressed by p-dinitrobenzene and hydroquinone. A single electron transfer initiated radical mechanism is proposed.
  • A new approach to .alpha.,.alpha.-difluoro-functionalized esters
    作者:Zhen Yu Yang、Donald J. Burton
    DOI:10.1021/jo00017a026
    日期:1991.8
    The addition reaction of iododifluoroacetates to alkenes is initiated by copper powder (10-20 mol %) at 50-60-degrees-C. Both terminal and internal alkenes give good yields of adducts. The reaction is also applicable to alkenes containing a variety of functional groups, such as epoxy, hydroxy, ketone, ester, and phosphonate moieties. This reaction can be carried out either neat or in solvents such as hexane, benzene, acetonitrile, DMF, DMSO, and HMPA and is suppressed by p-dinitrobenzene and di-tert-butyl nitroxide. A single electron transfer initiated radical mechanism is proposed. In the presence of nickel dichloride hexahydrate, reduction of the adducts with zinc in moist THF provides the corresponding alpha,alpha-difluoro esters in good yields.
