title: 1H, 13C and 15N NMR spectroscopy and tautomerism of nitrobenzotriazoles.
abstract: Benzotriazole nitro derivatives were prepared by nitration of the corresponding benzotriazoles and by methylation or cyclization of appropriate nitro-1,2-phenylenediamines. Structures and tautomerism of the nitrobenzotriazoles were studied by multinuclear (1)H, (13)C, (15)N, and 2D NMR spectroscopy and quantum chemistry.
