  Silver-Catalyzed C–H Trifluoromethylation of Arenes Using Trifluoroacetic Acid as the Trifluoromethylating Reagent

  摘要：

  Direct trifluoromethylation of arenes using TFA as the trifluoromethylating reagent was achieved with Ag as the catalyst. This reaction not only provides a new protocol for aryl CH trifluoromethylation, but the generation of CF3 from TFA may prove useful in other contexts and could potentially be extended to other trifluoromethylation reactions.

  Nickel complexes with simple naphthyridine ligands undergo facile aerobic oxidation to stable, isolated NiIII organometallic complexes, in which Ni–CF3 bond homolysis is observed upon irradiation with blue LED light. These complexes catalyze photoinduced C−H bond trifluoromethylation in arenes and heteroarenes.

  trifluoromethylation of (hetero)arenes with easily accessible C6F5I(OCOCF3)2 under photoredox catalysis has been developed. This method is tolerant of various (hetero)arenes and functional groups. Notably, C6F5I is recycled from the decarboxylation reaction and further used for the preparation of C6F5I(OCOCF3)2. The combination of photoredox catalysis and hypervalent iodine reagent provides a practical approach
