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
O,O-二烷基二硫代磷酸与烯胺加成的产物与具有亲电性质的第三反应组分,例如乙酰氯、α-溴醚或亚磺基溴反应。涉及亚磺基溴的反应产生亚胺盐和双(二烷氧基硫代磷酰硫基)二硫化物的C-Hal键的还原产物。这在实验上证实了 2-卤代醛或酮亚胺与硫代酸通过烯胺中间体发生反应。
