A novel mixed catalyst of LiClO 4 (15% w/w), Yb(OPf) 3 (15% w/w, Pf=perfluorooctanesulfonyl), MoO 3 (15% w/w) on silica gel for electrophilic aromatic nitration reaction has been explored. The nitration reactions were accomplished by this mixed catalyst and nitric acid under solvent‐free conditions. Moreover, the mixed catalyst can be easily recovered from the aqueous layer by heating in an oven and reused for the next nitration reaction.
