Phosphomolybdic acid hydrate encapsulated in MIL-53 (Fe): a novel heterogeneous heteropoly acid catalyst for ultrasound-assisted regioselective nitration of phenols

“…4,5 Nitrated phenols are one of the most important classes of the substituted aromatic compounds. 6 Besides, they are important synthetic intermediates and essential starting materials in advanced organic material synthesis, i.e. their reduction was a useful route to the corresponding aminophenols and synthesis of phenol-containing natural products.…”
