2, 2′-Diamino-4, 4′-diphenyl-5, 5′-dithiazolyl sulfone was synthesized by bromination of phenacyl sulfide in CHCl3 to dibromophenacyl sulfide, condensed with thiourea to 2, 2′-diamino-4, 4′-diphenyl-5, 5′-dithiazolyl sulfide which was oxidized to sulfone compound by H2O2 after acetylation and then hydrolyzed with HCl. From this fact, the position of Br was determined. An attempt to carry out this synthesis by the oxidation of phenacyl sulfide to the sulfone compound, its bromination to the dibromo compound and condensation with thiourea was not successful. The mechanism of this reaction and its product are now under study.
