A fluoroform‐derived borazine CF3− transfer reagent is used to effect rapid nucleophilic reactions in the absence of additives, within minutes at 25 °C. Inorganic electrophiles spanning seven groups of the periodic table can be trifluoromethylated in high yield, including transition metals used for catalytic trifluoromethylation. Organic electrophiles included (hetero)arenes, enabling C−H and C−X

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 fromdisulfides and diselenides.
