Abstract: Separate reaction of benzimidazolyl-2-guanidine and benzothiazolyl-2-guanidines with trichloroacetonitrile was investigated. 2,4-Diamino[1,3,5]triazino[1,2-a]benzimidazole and 2,4-diimino[1,3,5]triazino[2,1-a][1,3]benzothiazoles were found to be products of the reaction. The structures of the compounds obtained were established using 1H NMR spectroscopy.
Keywords: triazines, benzimidazoles, benzothiazoles, guanidines, cyclization
