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(SiMe3)2] (M=Na, K) as reagent. The new anionic entities are versatile PCN building blocks which allow the formation of a diversity of...
Derivate von Cyanophosphid, [PCN]2−, werden von H. Grützmacher, J. E. Borger et al. in ihrer Zuschrift auf S. 11551 synthetisiert. Die Zeichen Au, B und NHC beziehen sich auf die Substituenten, auf die PCN übertragen werden kann.
