A visible-light promoted bromotrifluoromethylation reaction of CF3Br with unactivated alkenes was achieved in the presence of catalytic amount of fac-IrIII(ppy)3. In the reaction, CF3Br serves as a bifunctional reagent to provide both the CF3 group and bromine source. The method features high regioselectivity, mild reaction conditions, high atom economy and good yields, which offers an economical and practical method for the construction of structurally diverse β-trifluoromethylated alkyl bromides.

Key words: visible-light catalysis, CF3Br, unactivated alkenes, bromotrifluoromethylation, bifunctional trifluoromethylating reagents
