Try Fe in AcOH or SnCl2 in EtOH (Tetrahedron Letters,Vol.25,No.8,pp 839-842,1984)

Mr. Kapse,

Try with the method in: B.Koleva, T. Kolev, R. Nikolova, Y. Zagraniarsky, M. Spiteller, Novel organic material with potential NLO application - electronic and spectroscopic properties, Central European Journal of Chemistry, 2008, 6, 592-599

An alkyl or aryl (R-NO2) could be reduced selectively into its respective alkyl or aryl amine (R-NH2) by using ammonium formate HCOONH4 with 10% Pd-C as catalyst & in CH30H as a medium.

Sodium dithionite is a good, mild choice. Here is a link to a nice org synth prep. http://www.orgsyn.org/demo.aspx?prep=cv3p0069

NO2 beside C=C in EtOH/H2O mixture: Zn/CaCl2 (Y>90%), NaHS, Na2S, Na2S2O4, TiCl3, FeSO4

Try to use Tin SnCl2 chloride

My group typically finds that either granular tin in HCl or SnCl2 work the best. You want to avoid iron species as a reducing agent if possible as the iron cations generated readily form coordination complexes with the resulting amine and can thus be quite difficult to remove if analytically pure products are desired.

Try Na2S in methanol. Polymer International 11/2009; 59(2):218 - 226

Iron or magnesium in presence of hydrochloric acid

You can reduce NO2 group using LiAlH4 in dry ether or THF , the double bond will remain in tact.

Thank you all for your kind suggestions, still I'm evaluating best method among your suggestions.

Thanks once again.

You can reduce No2 to amino group using LialH4 in dry ether

Pd/C with H2 is a very efficient way, veru easy, and the yields are usually very high

I have used Zn dust with acetic acid in DCM at roomtemp for reducing a phenylnitro to the phenylamine. The reaction can be slow but selective as the conditions are very mild.

you can try Zn dust with acetic acid (catalytic)in EtOH at roomtemp for reducing a phenylnitro to the phenylamine. The reaction could complete with in 1 hour.
