An E cient Method for the Nitration of Phenols with NaNO2 in the Presence of 3-Methyl-1-Sulfonic Acid Imidazolium Chloride
نویسنده
چکیده
Nitrophenols can be obtained in high yields via nitrosation-oxidation of phenols by 3methyl-1-sulfonic acid imidazolium chloride f[Msim]Clg as a new Br nsted acidic ionic liquid and NaNO2 at room temperature. In situ generation of HNO2 and a radical-cation mechanism via the nitrous acid catalyzed pathway appear to be applicable to phenol nitration using this reagent system.
