via trifluoromethylthiolation has been accomplished employing diaryl diselenide and AgSCF3 in the presence of BF3·OEt2. Various substituted 1,2-dichalcogenated products having the SCF3 moiety were synthesized in good to excellent yields under mild conditions. The preliminary mechanistic investigation revealed the possible reaction pathway and unique combination of diselenide and AgSCF3 for successful
