## Abstract Zinc powderโ€mediated reductive cyclization of __o__โ€nitrophenylazophenols in alkaline solution affords the corresponding 2โ€arylโ€2__H__โ€benzotriazoles in high yields under mild reaction conditions. __No organic solvents__ are used in the reaction and only minimal amounts in the workโ€up.
