dichlorides, and phenylenediamines containing electron-donating substituents are more reactive than those containing electron-withdrawing substituents. The diazaphosphole 2-oxides undergo hydrolysis or alcoholysis of only one of the amide groups under mild conditions. The 2-sulfides are much more resistant to hydrolysis than the 2-oxides. The 2-sulfides are converted to the N-methyl derivatives by dimethyl
已经制备了一系列 2,3-二氢-1H-1,3,2-苯并二氮杂磷 2-硫化物和 2-氧化物,最常见的方法是在回流惰性溶剂中将二胺与膦硫代或膦酰二氯化物缩合。硫代膦酰二氯化物比相应的膦酰二氯反应更慢,含有给电子取代基的苯二胺比含有吸电子取代基的苯二胺反应性更强。二氮杂磷酰 2-氧化物在温和条件下仅对其中一个酰胺基进行水解或醇解。2-硫化物比2-氧化物更耐水解。2-硫化物被硫酸二甲酯和碱转化为N-甲基衍生物。2-氧化物在这些条件下水解。
