Chhatbar,

FeCl3 has been used for this reaction using N-chlorosuccinimide as chlorinating agent, see

--- Tanemura, Kiyoshi et al  Halogenation of aromatic compounds by N-chloro-, N-bromo-, and N-iodosuccinimideو Chemistry Letters, 32(10), 932-933; 2003

ZnCl2 and LiCl had been reported as catalyst for this reaction using chlorine in 2 steps, see

--- Ewenson, Ariel et al  Process for electrophilic aromatic substitution   PCT Int. Appl., 9919275, 22 Apr 1999

However, trichloroisocyanuric acid in 98% sulfuric acid was reported to chlorinate nitrobenzene in 80%, see

Good luck

Method using isocyanuric acid trichloride mentioned by Adel Amer is very good. Reagent is used as chlorination disinfection tablets in pool chemicals. See

Thank you so much to Adel Amer  and Pazdera for their valuable and prompt reply.

I will try in the lab by Trichloroisocyanuric acid

Thanks once again

you may try using a HPA both as homogenious, and heterogeneous cats. In the latter case, I guess Сs salt of P-Mo acid will be a good choice.

Solid acid catalysts could be used.  I think that good selectivities have been shown by zeolite systems, e.g. HY. The Ultrastable form is likely to be the most successful. There are many recipes in the zeolite literature.
