Abstract

Abstract: Direct sulfinylation reaction of simple aromatic compounds by triflinate salts in triflic acid led to aryltrifluoromethyl sulfoxides. The para isomer was the major one. The regioselectivity of the reaction was very high when the substituent on the aromatic ring was a halogen atom, a trifluoromethoxy group or an acetanilide function. Key words: aryltrifluoromethylsulfoxides, sulfinylation, electrophilic reactions
