Abstract
Imidazotriazines are used as dyes, luminophores, and corrosion inhibitors [1, 2]. Earlier these compounds were obtained on the basis of diaminopyridinium salts, and this was not economically feasible. We decided to study an alternative method for the preparation of imidazotriazines starting from 1,2-diaminoimidazoles. In the course of the investigations we found that 1,2,3,4-tetrahydroimidazo[5,1-f][1,2,4]triazin-7-amines 4a-e are formed during the reaction of 1,2-diaminoimidazoles 1a-c, obtained by the reaction between benzaldehyde guanylhydrazones and halo ketones [1], with formaldehyde and primary amines 2a,b.
