4-bis(4-phen-oxyphenyl)-1,3,2,4-dithiaphosphetan is that 2, 3 and thionate most amides and lactams In THF at room temperature (reaction time 5 min) to give the corresponding thionated compounds. Imides are easily thionated by 2, 3 and 4 In DME at 60 °C. The reactions of 1 with amides, imides and most lactams are run at 60°C to give good yields of the corresponding thionated compounds.
2,4-双甲硫基-1,3,2,4-二硫代二膦,2,4-二硫,1,2,4-双(4-苯氧基苯基)-1,3,2,4-二硫代磷烷的硫磺化性质为即在室温下(反应时间为5分钟)将2、3和硫氰酸盐中的大部分酰胺和内酰胺溶于THF中,得到相应的亚硫代化合物。酰亚胺很容易在60°C下被2、3和4 In DME硫磺化。1与酰胺,酰亚胺和大多数内酰胺的反应在60°C下进行,以得到相应的亚硫代化合物良好的收率。
