The alkali decomposition of thioxolone was reported previously and the decomposition reaction of 5-chlorothioxolone (I) and 5, 7-dichlorothioxolone (I′) in alkaline solution was examined. Both I and I′, similar to thioxolone, became unstable as it became alkaline and were decomposed to 4-chloro-2-mercaptoresorcinol (II) and 4, 6-dichloro-2-mercaptoresorcinol (II′) respectively. The thiol compounds were oxidized to 2, 2′-dithiobis[4-chlororesorcinol] (III) and 2, 2′-dithiobis [4, 6-dichlororesorcinol] (III′). These reaction becomes slow as chlorine radical was introduced. These disulfide derivatives showed its reduction wave in acidic media by polarography, being supposed to be n=2.
