Abstract

A new method for the synthesis of aryl nitriles has been developed by the cyanation of aryl bromides with K₄Fe(CN)₆ as a cyanide source in the presence of Cu(OAc)₂.H₂O as an inexpensive catalyst and a 1,3-phenylene-bis- (1H)-tetrazole ligand. This method has the advantages of high yield, simple methodology and easy work-up.

Keywords: Aryl nitrile, 1, 3-Phenylene-bis-(1H)-tetrazole, Aryl bromide, Cyanation, K₄Fe(CN)₆, Copper acetate.
