Abstract Phosphine, generated from elemental phosphorus in the system KOH-toluene-H2O, reacts with vinyl sulfides under free radical conditions (AIBN, dioxane, 65–70°C, atmospheric pressure) to form regiospecifically tris[2-(organylthio)ethyl]phosphines, which are readily oxidized in air to corresponding tris[2-(organylthio)ethyl]phosphine oxides.
摘要 膦由 KOH-甲苯-H2O 系统中的元素磷生成,在自由基条件下(AIBN,二恶烷,65-70°C,大气压)与乙烯基硫化物反应,形成区域特异性三[2-(有机硫基)乙基]膦,在空气中很容易被氧化成相应的三[2-(有机硫基)乙基]氧化膦。
