Abstract

Trifluoromethylation of aromatic and hetero-aromatic compounds by CF 3I in the presence of Fe(II) compound, H 2O 2 and dimethylsulfoxide was investigated. Various trifluoromethylated benzene derivatives, six-membered nitrogen-containing aromatic compounds and five-membered hetero-aromatic compounds were obtained under mild conditions. General orientation of electrophilic substitution of aromatic compounds was observed similarly as reported in other radical trifluoromethylation previously.
