Reaction Steps

Copper (I) cyanide (5.05 g) was added to a stirred solution of 4-bromo-3-nitro-phenylsulphur pentafluoride (18.5 g) in N,N-dimethylformamide and heated at 140° C. for 4 hours. A mixture of ferric chloride (20.0 g),concentrated hydrochloric acid and water was added at 105° C. and heating continued for 1.25 hours. The cooled mixture was diluted with water, extracted (ether) and the organic phase washed (water), dried (magnesium sulphate) and evaporated to give 2-nitro-4-pentafluorosulphanylbenzonitrile (14.7 g), m.p.57°-590° C.
