Resumen:
Although 2-mercapto-5-methyl-1,3,4-thiadiazole (mmtd) is commonly thought of as a thione tautomer, electrophilic substitution occurs on the thiol moiety. The tautomeric ability of mmtd allows a substitution reaction to take place at the sulphur; this is shown by reaction with Cl3-nFnCSCI compounds (n = 0-2) to give perhalomethyldithio thiadiazole derivatives. Three novel perhalomethylsulphenyl compounds, which exhibit a wide range of potentially interesting applications, were obtained and characterized by x-ray crystal diffraction, mass spectrometry, IR and Raman spectroscopy and density functional theory calculations.
