Electrochemical reduction of N-nitroaminotetrazoles

Autor: V. N. Leibzon, A. G. Mayants, S. S. Gordeichuk

Publikováno v: Chemistry of Heterocyclic Compounds. 28:785-787

The electrochemical reduction of 5-nitroamino- and 2-methyl-5-nitroaminotetrazoles at the first wave potential consumes six electrons, while the reduction at the second wave potential consumes eight or nine electrons. The preparative reduction of 2-m
