  • Bromination of acetanilide by conventional method/green approach
  • Nitration of any one of the following:
  • Acetanilide/nitrobenzene by conventional method
  • Salicylic acid by green approach (using ceric ammonium nitrate).
  • Selective reduction of meta dinitrobenzene to m-nitroaniline.
  • Reduction of p-nitrobenzaldehyde by sodium borohydride.
  • Hydrolysis of amides and esters.
