New Synthesis of Benzotriazole Photostabilizers
Evans, Neil A.

1-(2-Nitrophenyl)-5-aryltetrazoles and 1-aryl-5-(2-nitrophenyl)tetrazoles are converted into 2-arylbenzotriazoles by the action of heat, the former reacting much faster than the latter.By appropriate use of methoxyl groups, useful benzotriazole ultraviolet absorbers may be synthesized conveniently by this method.
