(bpy)Zn(CF3)2 (bpy = 2,2′-bipyridine) at room temperature affords the corresponding ring-opening 1,3-aminotrifluoromethylation products in satisfactory yields. The protocol is highly regioselective, providing a convenient entry to γ-trifluoromethylated amines. A mechanism involving the trifluoromethylation of benzyl radicals is proposed.
芳基环丙烷,N-氟双(芳烃磺酰基)酰亚胺和(bpy)Zn(CF 3)2(bpy = 2,2'-联吡啶)在室温下的铜催化反应提供相应的开环1,3-氨基三氟甲基化产品产量令人满意。该方案具有很高的区域选择性,可方便地进入γ-三氟甲基化胺。提出了涉及苄基的三氟甲基化的机理。
