  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 activation of bonds with high bond dissociation energy and to substrates with high reduction potentials. Herein, we introduce a novel photocatalytic strategy for the activation of inert substituted arenes for aryl borylation by using thiolate as a catalyst. This catalytic system exhibits strong reducing ability and engages non-activated Caryl–F, Caryl–X, Caryl–O, Caryl–N, and Caryl–S bonds in productive

  目前正致力于获得具有高氧化还原能力的光氧化还原催化剂。然而，将目前建立的方法应用于具有高键离解能的键的活化和具有高还原电位的基材仍然具有挑战性。在此，我们介绍了一种新的光催化策略，通过使用硫醇盐作为催化剂来活化惰性取代芳烃以进行芳基硼化。该催化体系具有很强的还原能力，可与未活化的C芳基-F、C芳基-X、C芳基-O、C芳基-N和C芳基结合-S 键用于生产性自由基硼化反应，从而扩大了可用的芳基自由基前体范围。尽管具有很高的还原能力，但该方法具有广泛的底物范围和良好的官能团耐受性。光谱研究和控制实验表明，电荷转移复合物的形成是激活底物的关键步骤。

  Highly efficient, palladium-catalyzed, para-selective difluoromethylation of arene esters has been developed using [1,1′-biphenyl]-2-dicyclohexylphosphine as the effective ligand. A wide variety of arene esters bearing various functional groups were all compatible with the reaction conditions, leading to para-difluoromethylated products in moderate to good yields. Moreover, benzoylamide and benzenesulfonamide
