# Can aromatic rings be cyanated using cyanide as a nucleophile? [closed]

For example, can I convert chlorobenzene into benzonitrile by using potassium cyanide as the reagent?

• Replacing Cl in with CN is benzene can be done but requires a catalyst. Uncatalysed nothing with happen. – Waylander Nov 19 '18 at 19:28
• Can you please tell me the catalyst – SLADE Nov 19 '18 at 20:08
• There are many sets of conditions in the literature using Pd or Ni catalysis, more info here organic-chemistry.org/synthesis/C1C/arenes/cyanations.shtm – Waylander Nov 19 '18 at 21:04
• If possible, you'd rather start with iodoarenes. One of the well-established method uses copper(I) cyanide. Please see my answer to an earlier question, chemistry.stackexchange.com/questions/63892/… – Klaus-Dieter Warzecha Nov 20 '18 at 5:51
