New stable reagents for the nucleophilic trifluoromethylation. Part 4: Trifluoromethylation of disulfides and diselenides with hemiaminals of trifluoroacetaldehyde

Hemiaminals of fluoral and derivatives have been previously described as efficient new reagents for the nucleophilic trifluoromethylation of carbonyl compounds. Their use has been extended to the synthesis of trifluoromethyl sulfides and selenides from disulfides and diselenides.
