  Direct trifluoromethylation of C(sp3)–H bonds, especially in late stages, remains a formidable challenge. Herein, we describe the copper-catalyzed benzylic C(sp3)–H trifluoromethylation. With Cu(I) or Cu(II) as the catalyst, (bpy)Zn(CF3)2 (bpy = 2,2′-bipyridine) as the CF3 source, and NFSI (or Selectfluor) as the oxidant, site-selective benzylic C(sp3)–H trifluoromethylation is successfully implemented

  C（sp 3）–H键的直接三氟甲基化，尤其是在后期阶段，仍然是一个艰巨的挑战。在这里，我们描述了铜催化的苄基C（sp 3）–H三氟甲基化。以Cu（I）或Cu（II）为催化剂，以（bpy）Zn（CF 3）2（bpy = 2,2'-联吡啶）作为CF 3源，以NFSI（或Selectfluor）作为氧化剂选择性苄基C（sp 3）–H三氟甲基化已在温和条件下成功高效地实施。该协议不仅展示了广泛的底物范围和广泛的官能团兼容性，而且还允许对天然产物或药物衍生物进行有效的后期C（sp 3）–H三氟甲基化。

  The key Pd-catalyzed cross-coupling of aryl bromides or triflates and cyclopropylmagnesium bromide in the presence of substoichiometric amounts of zinc bromide produces cyclopropyl arenes in good to excellent yields. The cross-coupling of other alkyl, cycloalkyl, and aryl Grignard reagents with aryl bromides under the same conditions gives the corresponding substituted arenes in good yields.

  在亚化学计量的溴化锌存在下，芳基溴化物或三氟甲磺酸酯和环丙基溴化镁的关键Pd催化交叉偶联可以很好地获得优异收率的环丙基芳烃。在相同条件下，其他烷基，环烷基和芳基格氏试剂与芳基溴化物的交叉偶合可得到相应的取代芳烃，收率很高。
