SBA-15 supported Cu2O nanoparticles (Cu2O/SBA-15) have been fabricated and characterized. The as-prepared Cu2O/SBA-15 is a highly effective catalyst for cyanation of aryl iodides using non-toxic K-4[Fe(CN)(6)] as a cyanide source in dimethylformamide (DMF). The approach achieves a high selectivity and an excellent yield without using any ligands and base additives. Moreover, the Cu2O/SBA-15 catalyst shows wide functional group tolerance and reusability with a slight loss of activity.
