Participants

Reaction Steps

To an ice-cooled solution of 6.5 g (40 retool) of N-hydroxyphthalimide in 200 mL dry tetrahydrofuran (THF) was added 10.0 mL (15.8 g, 80 mmole) of trichloromethyl chloroformate (diphosgene). The solution was then stirred for 6 hrs at room temperature. The solvent and excess trichloromethyl chloroformate were removed under reduced pressure to give a white crystalline solid, which was recrystallized from dry n-hexane to give colorless plates; m.p. 113°-115° C.
