Melamine nitrate (MN) as a novel nitration reagent was easily prepared. Regioselective nitration of phenols to their corresponding o-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.
