modifications of tertiary arylphosphine oxides based on their reaction with sodium in liquid ammonia is presented. Depending on the structure of the starting compounds, either dearomatisation of the phenyl substituent or cleavage of a P-aryl bond from phosphorus atom can be selectively performed and the corresponding (1,4-cyclohexadien-3-yl)phosphine oxides or secondary phosphine oxides were obtained
提出了一种简单而实用的改性叔芳基膦氧化物的方法,该方法基于它们与液态氨中的钠反应。取决于起始化合物的结构,可以选择性地进行苯基取代基的脱芳香化或从磷原子上裂解一个P-芳基键,并且可以使用相应的(1,4-环己二-3-基)氧化膦或仲氧化膦。获得了高到极好的收率。
