Abstract Disodium 1, 6-disulfido-1, 3, 5-cycloheptatriene 3, formed by reduction of 1 with sodium in liq. ammonia, reacts with hydrogen chloride and methyl iodide to give 1, 6- dimercapto-, 4, and 1, 6-bis (methylthio)-1, 3, 5-cycloheptatrienes 5 respectively; however, it is oxidized by bromine to afford cyclic disulfide 6. 1, 6-Diiodo-1, 3, 5-cycloheptatriene 2 is converted to 1, 6-bis (benzylthio)-1, 3, 5-cycloheptatriene 7 by reaction with sodium ...
