REACTIONS OF α-MERCAPTOKETONES WITH P(III) AMIDES

α-Mercaptoketones react with P(III) amides in two directions, depending on the experimental conditions and environment of the phosphorus atom: the first yields 1,3,2-oxathiaphospholenes and open-chain dithiophosphates and the second involves sulfurization of the initial P(III) amide under the action of α-mercaptoketones.
