Abstract

A ZnO-supported palladium(0) nanoparticle catalyst has been applied for the efficient cyanation of a variety of functionalized aryl bromides and activated aryl chlorides with K4[Fe(CN)6] as benign cyanide source. This process circumvents the need for an additive and a ligand and offers high product yields, low catalyst loading (0.2 mol-% Pd), and recyclability of the catalyst.
