    Description / Table of Contents: Aminyl Oxides, XII. Determination and Reactions of Benzotriazolyl 1-OxideOxidation of 1-hydroxybenzotriazole (4) in the absence of oxygen yields benzotriazolyl 1-oxide (5), whereas in the presence of oxygen benzotriazolyl 1,3-dioxide (6) is formed. The reaction of 5 with benzene, thiophene, dimethyl acetylenedicarboxylate or 2,4,6-trimethoxybenzonitrile oxide results in nitrogen evolution and the formation of the product radicals 9, 10, 11 and 8c, respectively.
    Notes: Durch Oxidation des 1-Hydroxybenzotriazols (4) erhält man unter Sauerstoffausschluß das Benzotriazolyl-1-oxid-Radikal (5), in Gegenwart von Sauerstoff das Benzotriazolyl-1,3-dioxid (6). 5 reagiert unter N2-Abspaltung mit Benzol und Thiophen zu den Sekundärradikalen 9 bzw. 10, mit Acetylendicarbonsäure-dimethylester zu 11 und mit 2,4,6-Trimethoxybenzonitriloxid zu 8c.
