Abstract

The oxidation product bis(2-oxo-3H-1,3,4-thiadiazolidinyl)-5,5-disulfide (5b) was obtained from an attempted synthesis of 5-thioxo-3H,4H-1,3,4-thiadiazolidin-2-one (1). Spectroscopic results indicate that the most stable tautomeric form of 1 is the lactam-thiol form (1b). The computed total energies and relative energies at the MP4 level also showed that the most stable tautomer is 1b.
