Reaction of thiourea dioxides with amines

The reaction mechanism of thiourea dioxides with ammonia and primary aliphatic amines involves direct nucleophile (ammonia or amine) reactions with thiourea dioxides, followed by dissociation of the resulting adduct to form the sulfoxylate ion. 2004 MAIK "Nauka/Interperiodica".

Synthesis of Guanidino-1,3,5-triazines Using DMF

2,4,6-Triguanidino-1,3,5-triazine and 2,4,6-tris(3-methylguanidino)-1,3,5-triazine were synthesized in 42 and 52percent 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.
