An effective method for the synthesis of 4-amino-2,1,3-benzoselenadiazole (4) has been described. Reduction of readily available 4-nitrobenzothiadiazole 6 with SnCl2·2H2O afforded 1,2,3-triaminobenzene dihydrochloride 2. The latter u

Efficient hydrogenation of o-aminonitrobenzenes on palladium-containing granulated carbon catalysts in carboxylic acid solutions was accompanied by cyclization into aminobenzimidazoles. A simple hydrogenation reactor with a fixed gauze holding a reusable granulated catalyst was designed. Acylated and sulfonylated 4(7)-aminobenzimidazoles were obtained. In terms of electronic and geometrical parameters, they are close analogs of biologically active imidazo[1,5,4-e,f ][1,5]benzodiazepines.
