✦ Synopsis

In recent papers we have reported (1) that bis(o-aminophenyl)disulfide reacts with ketones to afford compounds of type (I) and (II). We have also shown that compounds (I) and (II) arise from the autoxidation of type (III) compounds; the latter can be isolated when the title reaction is run in absence of air.
