Melamine Nitrate: A Novel and Efficient Reagent for Regioselective Nitration of Phenols

摘要

Melamine nitrate (MN) as a novel nitration reagent was easily prepared. Regioselective nitration of phenols to their correspondingo-nitrophenols occurred using MN with p-toluenesulfonic acid as catalyst in good to excellent yields. A distinct advantage of this method is the easy separation of products by simple filtration.
