Phosphovanadomolybdic acid catalyzed direct C–H trifluoromethylation of (hetero)arenes using NaSO2CF3 as the CF3 source and O2 as the terminal oxidant

In the presence of phosphovanadomolybdic acids, a direct C–H trifluoromethylation of (hetero)arenes efficiently proceeded by utilizing NaSO₂CF₃ as the CF₃ source and O₂ as the terminal oxidant.
