Abstract

The N-benzyl-N-nitroso derivatives of 1- and 4-amino-1,2,4-triazoles, and 2-amino-5-phenyltetrazoles, 1-aminobenzotriazole, 7-amino-8-methyltheophylline, and 1-amino-3-methylbenzimidazol-2-one have been synthesized. The ratio of E- and Z-forms for them, arising as a result of hindered rotation about the N–N(O) bond, has been determined by  1H NMR spectroscopy. The energy of activation for the E↔Z
transition was estimated in several cases.
