Easy does it: Aryl boronic acids undergo smooth and selective trifluoromethylation with low‐cost fluoroform‐derived CuCF3 in DMF in non‐dried air. The reaction occurs under mild conditions (1 atm, room temperature), exhibits unprecedented functional‐group tolerance, and affords trifluoromethylated aromatic compounds in up to 99 % yield.
简单易行:在非干燥空气中,芳基硼酸在DMF中与低成本的氟仿衍生的CuCF 3进行平滑且选择性的三氟甲基化。该反应在温和的条件下(室温1个大气压)发生,显示出前所未有的官能团耐受性,并以高达99%的收率提供三氟甲基化的芳族化合物。
