Method of making hydroxyarylbenzotriazoles and their N-oxides |
| abstract |
Catalytic hydrogenation of o-nitrophenylazohydroxyaryls in an alkaline medium yields hydroxyarylbenzotriazoles; under mild conditions an N-oxide is formed. E.g., 6-tert-butyl-2-(5'-chloro-2'-nitrohenylazo)-p-cresol is hydrogenated to 5-chloro-2-(3'-tert-butyl-2'-hydroxy-5'-methylphenyl)benzotriazole, using platinum sulfide catalyst in the presence of sodium hydroxide: |
