of the reactions of phosphorus pentasulfide and Lawesson's reagent with a series of 4,5-bis(RCOCH2S)-1,3-dithiole-2-thiones (R=Ph, 4-MeOC6H4, 4-Br C6H4, Me) has been carried out. These reactions lead to fusion of either an unsaturated 1,4-dithiin ring or a thiophene to the dithiole; the former in higher yield, while the latter is a significant product in the reactions with Lawesson's reagent; as well
五硫化二磷和Lawesson与一系列的4,5-双(RCOCH试剂的反应的详细的研究2 S)-1,3-二硫杂环-2-硫酮(R =苯基,4- MeOC 6 ħ 4,4- Br C 6 H 4,Me)已经进行。这些反应导致不饱和的1,4-二硫辛环或噻吩与二硫醇融合;前者的收率较高,而后者是与劳森试剂反应的重要产物。以及少量次要产品。详细讨论了这些产品的机械合理性。新的稠合二硫醇已被转化为新颖的稠合TTF衍生物系列。
