General, practical and selective oxidation protocol for CF3s into CF3S(O) group

A simple and efficient protocol for the oxidation of trifluoromethyl, mono- and difluoromethyl sulfides to the corresponding sulfoxides without over-oxidation to sulfones, using TFPAA prepared in situ from trifluoroacetic acid and 15% H2O2 aqueous solution was developed. The methodology is suitable for a wide range of aromatic and aliphatic substrates in milligram and multigram scales.

Aryltrifluoromethylsulfoxides: Sulfinylation of aromatics by triflinate salts in acid medium

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.
