Reaction Steps

Pentafluorophenol (30 g; 163 mmol) and triethylamine (20 g, 200 mmol) were combined in 200 ml dry THF, and then added dropwise to a stirring solution of phosgene (20 g; 200 mmol) in 100 ml of toluene at 0° C. After 2 hours, the solution was filtered and evaporated to give the crude product as an oil, which was recrystallized from hexane to obtain 30 g (75%) pure pentafluorophenyl chloroformate.
