Radical C(sp2)-H trifluoromethylation of aromaticaldehydehydrazones is achieved in moderate to high yields under oxidative photoredox catalysis conditions, using inexpensive, bench-stable sodium trifluoromethanesulfinate (Langlois reagent), and Rose Bengal (RB) as the photocatalyst in the presence of acetic acid as the promoter. Acetic acid accelerates the rates of trifluoromethylation reactions
