Carbon disulphide and methyl iodide converted the anhydrobases (3) into 8-[(methylthio)thiocarbonyl]pyridinium iodides (4) which afforded new pyridinium anhydrobases (5) with ethoxide. These anhydrobases rearranged into the isomeric ketene S,S-dithioacetals (6), precursors for disulphides.
二硫化碳和甲基碘将脱水碱(3)转化为8-[((甲硫基)硫代羰基]吡啶碘化吡啶(4),从而提供了新的乙醇吡啶鎓脱水碱(5)。这些无水碱基重新排列成异构烯酮S,S-二硫缩醛(6),即二硫化物的前体。
