1 H -1,2,4-TRIAZOLO-5-DIAZONIUM SALTS IN THE SYNTHESIS OF NOVEL [1,2,4]TRIAZOLO[1,5- c ][1,2,4]BENZOTRIAZIN-6-OLS
Condensation of 1H-1,2,4-triazolo-5-diazonium salts with 1,3-cyclohexanedione, accompanied by cascade processes of cyclization and oxidative aromatization, brought about the synthesis of novel derivatives of [1,2,4]triazolo[5,1-c][1,2,4]benzotriazin-6-ols.
