  A Convenient Metal-Free Reagent for the Generation and Capture of Trifluoromethanethiol

  摘要：

  0-Octadecyl-S-trifluorothiolcarbonate is a cheap and storable crystalline source of trifluoromethanethiol that can be prepared in two steps on a multigram scale from trifluoroacetic anhydride and sodium 0-octadecyl-dithiocarbonate (xanthate). It reacts directly with gramines or with alpha-bromoketones and -esters in the presence of KF and pyrrolidine to give the corresponding trifluoromethyl sulfides in generally high yield.

  This work illustrates a reductive cross-electrophile coupling protocol for trifluoromethylation of alkyl iodides under Cu-catalyzed/Ni-promoted reaction conditions. The use of diboron esters as the terminal reductant allows the effective generation of the alkyl–CF3 products with excellent functional group tolerance and broad substrate scope. A mechanism involving a reaction of alkyl–Cu with Togni’s

  A visible-light-mediated hydrotrifluoromethylation of unactivated alkenes that uses the Umemoto reagent as the CF(3) source and MeOH as the reductant is disclosed. This effective transformation operates at room temperature in the presence of 5 mol % Ru(bpy)(3)Cl(2); the process is characterized by its operational simplicity and functional group tolerance.

  The copper-mediated trifluoromethylation of alkyl radicals is described. The combination of Et3SiH and K2S2O8 initiates the radical reactions of alkyl bromides or iodides with BPyCu(CF3)3 (BPy = 2,2'-bipyridine) in aqueous acetone at room temperature to afford the corresponding trifluoromethylation products in good yield. The protocol is applicable to various primary and secondary alkyl halides and

  日期：——

  A copper-catalyzed trifluoromethylation of aryl, vinyl and alkyl zinc reagents with Togni's reagent was described. Mechanistic studies indicated that the aryl group is initially transferred from the zinc reagent to hypervalent iodine to form a tri-substituted hypervalent iodine intermediate. Consequent reductive-elimination via a concerted bond-forming step and/or radical pathway from this intermediate

  描述了用Togni试剂进行铜催化的芳基，乙烯基和烷基锌试剂的三氟甲基化。机理研究表明，芳基最初从锌试剂转移到高价碘上，形成三取代的高价碘中间体。因此，通过该中间体的协同键形成步骤和/或自由基途径的还原消除作用产生了三氟甲基化的芳烃。
