Which kind of aryl are you interested in? The following paper could be interesting for you. DOI: 10.1039/B400878B; Chem. Commun., 2004, 888-889. -Using NaN3, CuI, L-proline, and a base in DMSO you can get in many cases good yields (you can find the details on the concentrations in the paper). -You can only use your iodide. Bromide possibly will not work using the above method. -Note that the presence of proline can really affect the yield of your reaction. I wish you find this method useful. Good Luck!

Thanks Raffaello Papadakis and Mahesh But for your valuable answers. Actually i am following the same article but i was using DMSO which did not work. Now i will try with mix solvent (EtOH/H2O) instead of DMSO.

Sayed, You can do it using sodium azide under Cu2O/tetraethylammonium prolinate catalysis in EtOH/EG. See ---Tetrahedron Letters, In Press, Corrected Proof, Available online 4 November 2014 Good Luck

You can reacting sodium azide with aryl bromide in presence of Cu-bronze catalyst.

You can convert by using NaN3 NaOH, EtOH, reflux 10 hrs.
You can get the article from this link http://pubs.rsc.org/en/content/articlehtml/2004/CC/B400878B

Aryl-bromide with electron withdrawing group at p-position w.r.t. Br in benzene with NaN3 may give Aryl azide.

I already synthesized from Aryl Iodide. Aryl bromide did not work in my case. Your valued suggestion is highly appreciated. Thanks a lot.
