Abstract
A study is made of the actions of thiourea and ammonia and alkali metal sulfides and hydrosulfides on 4 (5)-nitro-5 (4)-chloro (bromo) imidazoles. It is shown that, depending on the structure of the nitrohalogenoimidazoles, the nature of the sulfur compound, and the reaction conditions, the products are 4 (5)-nitro-5 (4)-mercaptoimidazoles, or their sulfides or disulfides. A convenient method of preparing nitromercaptoimidazoles, by reacting 4 (5)-nitro-5 (4)-chloroimidazoles with sodium sufide is offered.
