Abstract:

Nitrophenols can be obtained in moderate to high yields via nitrosation-oxidation of phenols with titania sulfuric acid, NaNO2 and wet SiO2 at room temperature. In situ generation of HNO2 and a radical cation mechanism via the nitrous acid catalyzed (NAC) pathway appear to be applicable to phenol nitration using these reagents.

Keywords:

Titania sulfuric acid , nitrosation-oxidation , nitration , nitrophenols
