2,4,6-Triguanidino-1,3,5-triazine and 2,4,6-tris(3-methylguanidino)-1,3,5-triazine were synthesized in 42 and 52% yields, respectively, by the cyclotrimerization of cyanoguanidine and 1-methyl-3-cyanoguanidine using DMF as a solvent in the presence of hydrogen chloride. 1-Phenyl-3-cyanoguanidine, 1,2-dimethyl-3-cyanoguanidine, and 2-imidazolidinylidenecyanamide, however, were cyclodimerized to the corresponding guanidino-1,3,5-triazines in a similar manner.
2,4,6-三氟胍基-1,3,5-三嗪和2,4,6-三(3-甲基胍基)-1,3,5-三嗪分别通过在盐酸存在下使用DMF作为溶剂对氰胍和1-甲基-3-氰胍进行环 trimerization合成,产率为42%和52%。然而,1-苯基-3-氰胍、1,2-二甲基-3-氰胍和2-咪唑啉基氰胺则以类似方式环二聚为相应的胍基-1,3,5-三嗪。
