Oxidation of diethyl disulfide with atmospheric oxygen at 363 К in the presence of 1,3-dimethylimidazolium dimethyl phosphate is described. On the basis of the 1 Н, 31 Р, and 13 С NMR data, it is shown that oxidation of diethyl disulfide results in ethyl sulfonates. Formation of ethyl alcohol, which is a product of a side reaction of ethyl sulfonate hydrolysis, probably, catalyzed by the 1,3-dimethylimidazolium cation, was detected using HPLC and 1 Н and 13 С NMR.

在 1,3-二甲基咪唑鎓二甲基磷酸酯存在下用大气氧氧化二乙基二硫化物

描述了在 1,3-二甲基咪唑鎓二甲基磷酸酯存在下用大气氧在 363 º 下氧化二乙基二硫醚。根据 1 Н、31 Р 和 13 С NMR 数据,表明二乙基二硫化物氧化生成乙基磺酸盐。乙醇的形成是磺酸乙酯水解副反应的产物,可能由 1,3-二甲基咪唑鎓阳离子催化,使用 HPLC 和 1 Н 和 13 С NMR 检测到。
