2-Chloro-4,5-dihydroimidazole 1 reacted with carbon disulfide to give 2,3,7,8-tetrahydro-5H-diimidazo<2,1-b:1',2'-e><1,3,5>thiadiazine-5-thione 5.Acid hydrolysis of 5 gave imidazoline-2-thione 6, which reacted with amines, dialkylhydrazines, and alkoxides to give thioureas 9, thiosemicarbazides 10 and thiocarbamates 11, respectively.Reaction of the hemisulfate of 1 with excess of potassium O-alkyl dithiocarbonates afforded diesters of thiodicarbonic acid 13.
