Acid-catalyzed decomposition of stable 1-(2,1-benzisothiazol-3-yl)-3-phenyltriazenes

Original language description

The acid-catalyzed decomposition of unusually stable 1-(2,1-benzisothiazol-3-yl)-3-phenyltriazenes in either aqueous perchloric acid or an aqueous mixture of perchloric and acetic acid was studied under pseudo-first order reaction conditions at 25 degrees C. Different products were obtained according to substitution on nitrogen N-3. An A-S(E)2 mechanism in which protonation of the triazene nitrogen proceeds simultaneously with cleavage of the N-N bond is proposed. Tautomerism of 1-(2,1-benzisothiazol-3-yl)3-phenyltriazene was investigated using H-1 NMR spectroscopy.
