Abstract

Abstract Dicyandiamide and aryldicyandiamides react with thiosemicarbazide to yield 1- amino-4-imino (or arylimino)-6-iminohexahydro-l, 3, 5-triazine-2-thiones. Acid hydrolysis of these compounds results in 3-amino-5-amino (or ary1amino)-1, 2, 4-triazoles with loss of thiocyanic acid, and their condensation with phenacyl bromide yields 8-amino (or arylamino)- 6-imino-3-phenyl-4H, 6H-[1, 3, 5] triazino-[2, 1-b][1, 3, 4] thiadiazines.
