Abstract
The adduct of O, O-dialkyldithiophosphoric acid and enamine reacts exothermically with an electrophilic reagent. In the case of sulfenyl bromide, the iminium salt reduced at the C-Br bond and bis(dialkoxythiophosphorylthio)-disulfide have been formed, experimentally evidencing the reaction of 2-halogenated ald- and ketimines with dithioic acid via the intermediate formation of enamine.
