β-Diethoxyphosphorylethyl sulphoxides 4, prepared by selective oxidation of the corresponding sulphides 6 using bromine/potassium hydrogen carbonate as oxidising agent in a two-phase system, undergo the Pummerer rearrangement accompanied by elimination affording E-β-ethylthio-vinylphosphonate 7. The synthesis of Z-α-bromo-β-ethylthiovinylphosphonate 14 is also described.
通过在两相系统中使用溴/碳酸氢钾作为氧化剂对相应的硫化物6进行选择性氧化而制得的β-二乙氧基磷酰基乙基亚砜4经过Pummerer重排并消除,得到E-β-乙基硫代乙烯基膦酸酯7。还描述了Z-α-溴-β-乙基硫代乙烯基膦酸酯14的合成。
