A few phosphinicacids, 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

Phosphinamides based on the 7-phosphanorbornene framework can be reduced with HSiCl3–C5H5N to give phosphinous chlorides which have remarkable chemical and 31P n.m.r.properties and a strong preference for an anti-configuration of chlorine.
可以用HSiCl 3 -C 5 H 5 N还原基于7-膦基降冰片烯骨架的膦酰胺,得到具有显着化学和31 P nmr性质的亚膦酰氯,并且强烈偏爱氯的抗构型。
