SYNTHESES AND TRANSFORMATIONS OF SUBSTITUTED BENZAZOLYL(BENZOTRIAZOL-1-YL)METHANES AND TETRAZOLYL(BENZOTRIAZOL-1-YL)METHANES

Condensation reactions of o-hydroxy- and o-mercaptoanilines, and o-phe nylenediamine with (benzotriazol-1-yl)acetic acid result in (1,3-benza zol-2-yl) (benzotriazol-1-yl)methanes. Cycloaddition of sodium azide t o (benzotriazol-1-yl) acetonitrile leads to (1,2,3,4-tetrazol-5-yl) (b enzotriazol-1-yl)methane. The diazolo-substituted benzotriazolylmethan es thus obtained were mono- and di-alkylated at the methylene group an d the displacement of the benzotriazole group by nucleophiles was inve stigated.
