Benzene is nitrated by a novel atom-economic nitration procedure with a NO2-O-2 system in the presence of a mixture of solid oxides and Ln(OTf)(3). The only by-product in this novel method is water. The efficiency of NO2 is much high than 50%, the theoretical efficiency of NO2 of the known methods. Among the solid oxides and Ln(OTf)(3) studied, HZSM-5 and Sm(OTf)(3) were the most efficient catalysts in this process. Therewith, the yield of the benzene nitration reached 72.5%, calculated by NO2.
