  作者：Liuzhou Gao、Guoqiang Wang、Jia Cao、Dandan Yuan、Cheng Xu、Xuewen Guo、Shuhua Li

  DOI：10.1039/c8cc06152a

  日期：——

  The decarboxylative alkylation of N-hydroxyphthalimide (NHPI) based reactive esters with olefins has been achieved via an organocatalytic strategy. Control experiments and density functional theory calculations suggest that these reactions involve a boryl-radical mediated decarboxylation pathway, which is different from the single electron transfer involved in decarboxylative alkylation reactions reported

  N-羟基邻苯二甲酰亚胺（NHPI）基反应性酯与烯烃的脱羧烷基化已通过有机催化策略实现。对照实验和密度泛函理论计算表明，这些反应涉及硼基自由基介导的脱羧途径，该途径不同于先前报道的脱羧烷基化反应中涉及的单电子转移。这种无金属的脱羧烷基化反应具有良好的功能相容性，并且通过烷基和芳基羧酸衍生物的转化说明了广泛的底物范围。

  Herein, a copper‐catalyzed C−F bond defluorosilylation reaction of tetrafluoroethylene and other polyfluoroalkenes is described. Mechanistic studies, based on a series of stoichiometric reactions with copper complexes, revealed that the key steps of this defluorosilylation reaction are 1) the 1,2‐addition of a silylcopper intermediate to the polyfluoroalkene and 2) a subsequent selective β‐fluorine

• Palladium-Catalyzed Trimethylenemethane Cycloaddition of Olefins Activated by the σ-Electron-Withdrawing Trifluoromethyl Group
  作者：Barry M. Trost、Laurent Debien

  DOI：10.1021/jacs.5b07573

  日期：2015.9.16

  α-Trifluoromethyl-styrenes, trifluoromethyl-enynes, and dienes undergo palladium-catalyzed trimethylenemethane cycloadditions under mild reaction conditions. The trifluoromethyl group serves as a unique σ-electron-withdrawing group for the activation of the olefin toward the cycloaddition. This method allows for the formation of exomethylene cyclopentanes bearing a quaternary center substituted by
