Imidazole → Thionyldiimidazole

Participants

Reaction Steps

Imidazole (43.2 g, 635 mmol) was dissolved in tetrahydrofuran (100 ml), and under ice cooling, thionyl chloride (23.5 g, 199 mmol) was added thereto. The reaction mixture was stirred for 3 hours at room temperature, and then the salt thus produced was separated by filtration. Thus, a sulfinyldiimidazole solution was obtained.
