The direct C−H trifluoromethylation of arenes catalyzed by graphene oxide (GO) under safe conditions is described. This strategy is metal‐free, initiator‐free, safe, and scalable. It employs a readily available CF3 source and the reaction can be easily controlled to obtain a mono‐trifluorinated product. This method opens a new avenue for GO‐catalyzed chemistry.

An efficient, practical, catalyst-free direct C–H trifluoromethylation of arenes using readily available and inexpensive CF3SO2Na as a CF3-source in water–acetonitrile is described.
AbstractWe report the visible‐light‐induced trifluoromethylation of arenes and heteroarenes using sodium trifluoromethanesulfinate catalyzed by anthraquinone‐2‐carboxylic acid. This reaction is a metal‐free trifluoromethylation of arenes and heteroarenes catalyzed by a photoredox organocatalyst. Perfluoroalkylated arenes were also produced using sodium perfluoroalkylsulfinates.magnified image

A copper-mediated oxidative cross-coupling of aryl- and alkenylboronic acids with (trifluoromethyl)trimethylsilane (Me3SiCF3) under mild conditions has been developed. This method allows a wide range of functional group tolerant trifluoromethylated arenes and alkenes to be easily prepared. This oxidative trifluoromethylation has the potential to introduce trifluoromethyl groups into advanced, highly
