RESEARCH REGARDING SYNTHESIS AND BIOLOGICAL ACTIVITY OF 1,2,4-DITHIAZOLE-3,5-DISUBSTITUTED SALTS. II. OBTAINING AND CHARACTERIZATION
In the latest studies in this field, a great attention was paid on the dithiazolium salts disubstituted in positions 3, 5 with phenyl radicals or substituted-phenyl <1-7>. The synthesis of these compounds has been patented because they are of applied interest. The researches performed in the Departement of Organic Chemistry concerning the synthesis of 3,5-disubstituted dithiazolium salts have been extended about the compounds substituted with stiryl radicals and vinylen-heterocycles <8-12>. In this paper we have proposed a comparative study on the synthesis of the 3,5-disubstituted-1,2,4-dithiazolium tribromides and triiodides in order to establish the optimal reaction conditions and to establish the structures of the new synthetised compounds.
