  磷烯氧化物的异构化及应用

  摘要：

  摘要 本研究对3-磷烯氧化物的异构化及其应用进行了研究。在热条件下研究了 3-磷烯氧化物异构化为 2-磷烯氧化物。在该反应中还测试了碱和酸的应用。此外，异构化也通过形成卤代鏻盐中间体来进行。3-磷烯氧化物被脱氧并转化为相应的钯配合物。图形概要

  obtained by heating the 3-phospholene oxides in methanesulfonic acid, or via the formation of cyclic chlorophosphonium salts. Whereas mixtures of the 2- and 3-phospholene oxides formed, when the isomerization of 3-phospholene oxides was attempted under thermal conditions, or in the presence of a base. The mechanisms of the various double bond migration pathways were elucidated by quantum chemical calculations

  通过双键重排，由相应的3-氧化膦制备一系列1-取代的-3-甲基-2-氧化膦。可以通过在甲磺酸中加热3-氧化膦或通过形成环状氯膦盐来获得2-氧化膦。然而，当在热条件下或在碱的存在下尝试3-环氧丙烷的异构化时，形成了2-环氧丙烷和3-环氧丙烷的混合物。量子化学计算阐明了各种双键迁移途径的机理。
