Magnetic graphitic carbon nitride Fe@g-C3N4 has been synthesized by adorning a graphitic carbon nitride (g-C3N4) support with iron oxide via non-covalent interaction. The magnetically recyclable catalyst showed excellent reactivity for the expeditious C–H activation and cyanation of amines.

A sustainable protocol for the α-cyanation of amines has been developed using cheap and affordable iron oxide nanoparticles under acid free conditions with an easy-to-handle, user-friendly cyanidesource, ethyl cyanoformate. The magnetic property of the iron oxide nanoparticles facilitated their easy recovery and the recovered particles were found to be reusable up to five cycles with no loss of activity
