A Novel Cyanation Reaction of Arenes Using Acetonitrile as a Cyano Source

A0060

[Experimental Procedure]
Cyanation of Cumene (R=i-Pr) : An oven-dried Schlenk tube equipped with a magnetic stir bar is evacuated and backfilled with O2 three times. Cumene (0.5 mmol), N-iodosuccinimide (NIS) (1.05 eq., 0.525 mmol), Cu(ClO4)2·6H2O (20 mol%, 0.1 mmol), acetonitrile (1.2 mL) are added into the tube and the reaction is stirred at 150°C for 1 hour. The reaction mixture is allowed to cool down. Under O2, 1,10-phenanthroline (20 mol%, 0.1 mmol), TEMPO free radical (2 eq., 1 mmol), hexamethyldisilane (1 eq., 0.5 mmol) are added into the reaction mixture. The reaction is then heated up to 150°C for 2.5 days under O2. After completion, the insoluble is removed by filtration. The filtrate is concentrated under vacuo and the residue is purified by column chromatography on silica gel using EtOAc / petroleum ether to give the corresponding p- or o-cyanated cumenes as a yellow liquid (65 mg, 90% yield, p:o = 6:1).
