Participants

Reaction Steps

To 3-(5tetrazolyl)thioxanthone-10,10-dioxide (1.25 g.), zinc wool (2.50 g.) and mercuric acetate (0.10 g.) was added acetic acid (25 ml.) and concentrated hydrochloric acid (25 ml.) and the mixture boiled under reflux for 2 hr. After this time a further amount of hydrochloric acid (1.5 ml.) was added and the mixture boiled for a further 4 hr., filtered while hot, cooled, and diluted with water. The crude product was filtered off, recrystallised three times from methanol, and dried at 80° C. in vacuo to give 3-(5-tetrazolyl)thioxanthene-10,10-dioxide m.pt. 233° C. with decomposition.
