| Abstract: | Nitroarenes were shown by us earlier to undergo reduction when treated with Al/NH4Cl in methanol under sonic conditions to give anilines in high yields [D. Nagaraja, M.A. Pasha, Tetrahedron Lett. 40 (1999) 7855]. Now, a comparative study has been carried out and an efficient and improved procedure for this reduction by using Al/NH4X (X=Cl, Br, I) is reported. A plausible mechanism of the reaction is envisaged. |
