Benzene → Pentafluoroethylphenyliodonium trifluoromethanesulfonate

Participants

Reaction Steps

To a mixture of 6.05 g of di(trifluoroacetoxy)iodopentafluoroethane and 45 ml of trifluoroacetic acid was added 1.1 ml of trifluoromethanesulfonic acid while cooling in an ice bath and stirring, and thereafter 1.2 ml of benzene was added dropwise to the mixture. After completion of the addition, the mixture was stirred for 4.5 hours and the solvent was distilled off to obtain a crystalline solid which was then recrystallized from chloroform to obtain 3.32 g (55% yield) of pentafluoroethylphenyliodonium trifluoromethanesulfonate as colorless flake crystals.
