2,4-Bis(4-methoxyphenyl)-1,3,2,4-dithiadiphosphetane-2,4-disulfide (Lawesson's Reagent) and its p-phenoxy derivative react with o-dihydroxybenzene derivatives, dihydroxy naphthalene and 2,2-dihydroxybiphenyl in toluene at reflux temperature to give 1,3,2-dioxaphospholane-2-sulfide derivatives, 3a–f, 8a,b and 11a,b respectively. The structure of the products has established either chemically using methanolysis
2,4-双(4-甲氧基苯基)-1,3,2,4-二硫代二膦-2,4-二硫化物(Lawesson试剂)及其对苯氧基衍生物与邻二羟基苯衍生物,二羟基萘和2,2-甲苯在回流温度下的二羟基联苯,分别得到1,3,2-二氧杂膦烷-2-硫化物衍生物3a-f,8a,b和11a,b。产品的结构已通过化学方法使用甲醇分解和甲基化方法建立,或通过光谱法确定。而且,已经使用了分析数据。讨论了有关上述产物形成的机械考虑。
