Synthesis and Thermal Stability of 4-Substituted 1,2-Dithiolanes

Disodium 2-cyano-3,3-bis(sulfido)propenamide (6) has been used as a double synthon for SH- in the preparation of 1,3-dithiols.Oxidation of the dithiols gives 4-substituted 1,2-dithiolanes, e.g. asparagusic acid (3).The energy splits between the first and second ionization potantials in 3 and the other 1,2-dithiolanes (8-11) have been determined by ultraviolet photoelectron spectroscopy.The relative stability of these compounds do not correlate with the measured ΔE values.Hence, factors besides the S-S torsional angle must influence these stabilities.
