Trifluoromethanesulfonic acid → Diphenyliodonium trifluoromethanesulfonate

Participants

Reaction Steps

Diphenyliodonium dimethylphosphate (315 mg; 1 mmol) and trifluoromethanesulfonic acid (158 mg; 1.01 mmol) were dissolved in methylene chloride (10 ml), and the resultant mixture was stirred. Half volume of the solvent was removed from the methylene chloride solution through distillation, and ether (50 ml) was added thereto. The mixture was stirred, to thereby precipitate 109 mg of the target compound as white crystals (yield: 72%).
