A few phosphinic acids, such as phenylphosphinic acids, 1-hydroxy-3-phospholene 1-oxides and 1-hydroxyphospholane oxides are esterified with simple alcohols in the presence of propylphosphonic anhydride (T3P®). If 1.1 equiv of the T3P® reagent is used, the esterifications are fast and efficient at 25° C. In the case of more reactive models it was enough to apply 0.66 equiv of T3P® at 85° C under microwave
少数次膦酸,苯基次作为酸,1-羟基-3-环磷-1-氧化物和1- hydroxyphospholane氧化物,例如酯化,在丙基膦酸酐(T3P的存在简单的醇®)。如果T3P的1.1当量®使用试剂时,酯化是快速和有效的在25℃下在多种反应性模型它足以适用0.66当量T3P的情况下®在85℃在微波条件下。1-羟基-3-甲基-3-氧化膦的酰胺化也可以在类似条件下完成。
