Abstract:

The investigation about different seleniumcontaining heterocyclic compounds has expanded rapidly during last years. Furthermore, substituted benzochalcogenazole systems have presented also interesting pharmaceutical properties. Besides, the synthesis of 2-substituted-1,3-benzothiazoles have attracted much attention according to their notably photophysical properties. Our continuing interest on the synthesis of organoselenium compounds prompted us to explore a general procedure to obtain 2-substituted 1,3-benzoselenazoles from bis(2-aminophenyl) diselenide (1a) and carboxylic acids (2a-m), using tributylphosphine in toluene under conventional heating or microwave irradiation (scheme 1).
