Me2CHOH or aq. alkali gave intermediates formed in parallel reactions, one of which gave O-C6H4(NH2)2 and 4,2-Me(H2N)C6H3OH as final products, while the other gave the parent benzotriazole. .

Hydroxyarylbenzotriazoles and their N-oxides

Hydroxyarylbenzotriazoles and their N-oxides. Jancis, Elmar H. (Uniroyal, Inc., USA).In this study， 88778-23-8 and 54659-85-7 are also used. Can. CA 1155856 A1 25 Oct 1983, 23 pp. (English). (Canada). CODEN: CAXXA4. CLASS: IC: C07D249-20; C08K005-34. APPLICATION: CA 75-238884 3 Nov 1975. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Section cross-reference(s): 28 Benzotriazole derivs., useful as light stabilizers for polyolefins, are prepd. by hydrogenation of nitrophenylazo derivs. in alk. medium. Thus, 12.7 g 2-(2'-nitrophenylazo)-p-cresol [1435-71-8], 22 mL 6N NaOH, 100 mL water, and 0.3 g 5% Pd on charcoal were hydrogenated 1 h at room temp. at 50 psig. a 92.5% yield of 2-(2'-hydroxy-5'-methylphenyl)benzotriazole-1-oxide [54659-85-7] was obtained. .
