Abstract
The heating of the hydrate of 5-diazomethylazotetrazole in an aqueous medium led to the isolation, for the first time, of 5-hydroxymethylazotetrazole — the proposed intermediate product in the isolation of 5-hydrazinotetrazole from 5-diazomethylazotetrazole in acidic media. It was established that 5-hydrazinotetrazole is not formed when 5-hydroxymethylazotetrazole is treated with hydrochloric acid under different conditions. In this connection, an improved reaction mechanism, not including 5-hydroxymethylazotetrazole as an intermediate compound, was proposed. It was shown that not all of the 5-diazomethylazotetrazole enters into the reaction with water. The proposition was expressed that the product which did not enter into the reaction is the Z-isomer.
