The reaction of singlet oxygen with tetrakis(ethylthio)ethylene has been shown to afford diethylthiooxalate and diethyl disulfide. The expected diethylthiocarbonate was also obtained as a minor product. A similar reaction with bis(ethylthio)ethylene gave ethylthioglyoxalate together with diethyl disulfide. Formation of diethylthioacetaldehyde was also observed, and is suggested to proceed via the intermediary
单线态氧与四(乙硫基)乙烯的反应已显示出提供二乙硫草酸酯和二乙二硫醚。也获得了次要产物预期的二乙基硫代碳酸氢盐。与双(乙硫基)乙烯的类似反应得到乙硫基乙二酸酯和二乙基二硫化物。还观察到二乙硫基乙醛的形成,建议通过中间体1,2-二氧杂环丁烷或过环氧化物进行,然后优先转移乙基tilio基团。另一方面,苯硫基乙烯被单线态氧氧化,得到硫醇酯和二硫化物。这表明二硫化物的形成可能通过自由基途径发生。还研究了二硫化物在醇中的光氧化作用。
