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.

O-dialkyldithiophosphoric acid to enamine reacted with the third reaction component of electrophilic nature, for instance, acetyl chloride, α-bromo ether, or sulfenyl bromide. The reaction involving sulfenyl bromide gave the product of reduction of the C—Hal bond of iminium salt and bis(dialkoxythiophosphorylthio) disulfide. This experimentally confirmed the occurrence of the reaction between 2-halo-substituted
