Reaction Steps
A mixture of 95 grams (0.5 moles) of 2,5-dimercapto-1,3,4-thiadiazole and 49.0 grams (0.5 moles) of maleic anhydride in 500 ml. tetrahydrofuran was refluxed for six hours. After distilling off the solvent, a light tan solid (123 g.) was obtained (m.p. 194°-196° C.). Its infrared spectrum and elemental analysis appeared to be consistent with the proposed structure.
