  Copper-mediated trifluoromethylation of potassium alkynyltrifluoroborates with Langlois' reagent

  摘要：

  Synthesis of trifluoromethylated acetylenes by copper-mediated trifluoromethylation of potassium alkynyltrifluoroborates with CF3 radicals generated from NaSO2CF3 and tert-butyl hydroperoxide (TBHP) is communicated. The trifluoromethylated acetylenes were obtained in good to moderate yields. The presented method tolerates a wide range of aromatic, heteroaromatic, and aliphatic potassium alkynyltrifluoroborates.

  The first organocopper(III) fluoride, [PPh4][CuIII(CF3)3F] (2), has been isolated and authenticated. Despite its stability, 2 reacts with alkynylsilanes leading to industrially relevant trifluoromethylalkynes (RC≡CCF3). Mechanistic investigations, including the trapping of [PPh4][CuIII(CF3)3(C≡CPh)] (4a), validates the operability of a CuI/CuIII redox shuttle in oxidative C−C couplings occurring through

  第一种氟化有机铜(III) [PPh 4 ][Cu III (CF 3 ) 3 F] ( 2 ) 已被分离和鉴定。尽管具有稳定性， 2仍会与炔基硅烷发生反应，生成工业相关的三氟甲基炔烃 (RC≡CCF 3 )。机理研究，包括捕获 [PPh 4 ][Cu III (CF 3 ) 3 (CQICPh)] ( 4 a )，验证了 Cu I /Cu III氧化还原穿梭在氧化 C−C 偶联中的可操作性迄今为止难以捉摸的有机铜(III)氟化物。
