The old one two: A sequential iridium‐catalyzed borylation and copper‐catalyzed trifluoromethylation of arenes is described (see scheme; Pin=pinacol). The reaction is conducted under mild reaction conditions and tolerates a variety of functional groups. The advantages of this tandem procedure are demonstrated by the late‐stage trifluoromethylation of a number of biologically active molecules.
旧的两个描述了铱的连续铱催化的硼化和铜催化的三氟甲基化(参见方案; Pin =频哪醇)。该反应在温和的反应条件下进行,并能耐受多种官能团。许多生物活性分子的晚期三氟甲基化证明了这种串联方法的优势。
