Copper Iodide Nanoparticles-Catalysed Cyanation of Aryl Halides Using Non-Toxic K ₄ [Fe(CN) ₆ ] in the Presence of 1,2-Bis(5-Tetrazolyl)Benzene as an Efficient Ligand

Cyanation of aryl bromides were carried out with K 4 [Fe(CN) 6 ] in the presence of catalytic amounts of a copper salt and 1,2-bis(5-tetrazolyl)benzene as a ligand under thermal conditions. This method has the advantages of high yields, simple methodology and easy work up.
