Abstract
A number of new 4-imino-substituted 2-methyl-7,8-diphenyl-5H-imidazo[1,2-b]-1,2,4-triazepines were synthesized by replacing the S atom in 2-methyl-7,8-diphenyl-5H-imidazo[1,2-b]-1,2,4-triazepine-4-thione by the action of nitrogen-containing nucleophiles. It is shown that the imine form is characteristic for the synthesized compounds.
