Sunlight-induced decomposition of hydroxytriazenes, and green photochemical synthesis of azo-dyes is described. Three substituted hydroxytriazenes, viz: 3-hydroxy-3-(2-methylphenyl)-1-(3-chloro-4-fluorophenyl)triazene (o-CFHT), 3-hydroxy-3-(3-methylphenyl)-1-(3-chloro-4-fluorophenyl)triazene (m-CFHT), and 3-hydroxy-3-(4-methylphenyl)-1-(3-chloro-4-fluorophenyl)triazene (p-CFHT) were co-crystallized with β-naphthol in equimolar ratio and exposed to sunlight for 9-10h. The reaction resulted in formation of azo-dyes which were identified by comparison with the products obtained by the conventional method (standard azodye), by use of HPLC. A probable mechanism has been suggested. This is first ecofriendly synthesis of azo-dyes using hydroxytriazenes. Springer Science+Business Media B.V. 2012.
