The facile preparation of alkali salts of phosphanyl cyanophosphides [NHP‐PCN] − (NHP=N‐heterocyclic phosphenium) is reported. Their formation is achieved by isoelectronic replacement of O for [N] − in the phosphaketenes NHP‐PCO using alkaline hexamethyldisilazide M[N(SiMe 3 ) 2 ] (M=Na, K) as reagent. The new anionic entities are versatile PCN building blocks which allow the formation of a diversity of new cyanophosphine derivates including the first example of a PCNB hetero‐cumulene and a PCN‐ligated transition metal complex.
