N-NITRATION OF 5-AMINOTETRAZOLE BY TETRANITROMETHANE, HEXANITROETHANE, AND PENTAERYTHRITOL TETRANITRATE

Mayants, A. G.,Pyreseva, K. G.,Gordeichuk, S. S.

, p. 798 - 801 (2007/10/02)

The N-nitration of 5-aminotetrazole with tetranitromethane, hexanitroethane, and pentaerythritol tetranitrate in the presence of strong alkaline agents leads to the formation of the corresponding salts of 5-nitroaminotetrazole.In contrast to this, a salt of azotetrazole is formed in addition to the 5-nitroaminotetrazole salt during nitration with tetranitromethane in the presence of a weakly alkaline agent (sodium bicarbonate).
