Phosphine imide - Wikipedia

In chemistry a phosphine imide (sometimes abbreviated to phosphinimide) also known as a iminophosphorane is a functional group with the formula R3P=NR. While structurally related to phosphine oxide its chemistry has more in common with phosphonium ylides. Anions of this group, with the … Zobacz więcej Phosphine imides can be isolated as intermediates in the Staudinger reaction and have also been prepared by the action of hydroxylamine-O-sulfonic acid on phosphines, proceeding via a p-aminophosphonium … Zobacz więcej The functional group will readily hydrolyse to give a phosphine oxide and an amine R3P=NR' + H2O → R3P=O + R'NH2 Phosphinimide ligands Zobacz więcej • Aminophosphine • Phosphazene Zobacz więcej WitrynaThe resulting three membered ring system can be considered as a complex of two iminophosphanes.
