A Mild Procedure for the Preparation of o-Nitrophenols by Nitro Urea or Ammonium Nitrate in the Presence of Silica Sulfuric Acid (SiO2-OSO3H)

A mixture of ammonium nitrate or nitro urea and silica sulfuric acid was found to be efficient and environmentally friendly nitrating media for the preparation of orto‐nitro phenols in dichloromethane at room temperature. A mixture of ammonium nitrate or nitro urea and silica sulfuric acid was found...
