| Popis: | Iminophosphoranes are organic compounds of general composition R3P=NR and can be considered as nitrogen analogues to phophorus ylides. They can be obtained by the Staudinger[1] and Kirsanov[2] reactions. This compounds have multiple applications: they can be used as intermediates in reactions such as the Aza-Wittig[3], as a protecting group for amines or as a ligands for coordinated or cyclometallated compounds[4]. The P=N bond is highly polarized, so that the nitrogen bears a partial negative charge. This feature makes them act as σ-donors with only minor π-acceptor properties, so when forming coordination compounds they can be displaced by other ligands[5].
