A straightforward process to aminate pyridines and diazines is presented by reacting phosphonium salt derivatives with sodium azide. The iminophosphorane products are versatile precursors to several nitrogen-containing functional groups, and the process can be applied to building block heterocycles, to drug-like fragments, and for late-stage functionalization of complex pharmaceuticals.

C3-selective cyanation of pyridines was accomplished by a tandem process of borane-catalyzed pyridine hydroboration, substitution of the resulting dihydropyridine with a cyano electrophile, and finally oxidative aromatization. This method was suitable for use in late-stage cyanation of pyridine drugs.
