NHC-Mediated Synthesis of an Asymmetric, Cationic Phosphoranide, a Phosphanide, and Coinage-Metal Phosphanido Complexes

A cationic phosphoranide featuring a normal and an abnormal imidazoliumyl substituent was prepared through the reaction of a P‐centered cation with an N‐heterocyclic carbene (NHC). The remarkable reactivity of this compound allows the formation of two‐ or three‐coordinate P‐centered cations, illustrating the ability of imidazoliumyl substituents to stabilize high‐ and low‐coordinated P atoms.
