Abstract

A facile, one-pot reaction between 3, 4, 5-triamino-1, 2, 4-triazole (guanazine) and cyanogen bromide provides a new high-nitrogen example of the 3H, 9H-bis [1, 2, 4] triazolo [1, 5-a: 5′, 1′-d][1, 3, 5] triazinium system, the 2, 3, 5, 6-tetraamino-9-imino derivative (3) as a quaternary bromide salt.
