Phenol (I) is nitrated regioselectively by fuming nitric acid inside the cages of faujasite zeolites. While nitration as hexane slurry in CsY and molecular sieve 5 ร… leads to predominant formation of para-nitrophenol (III), a remarkable ortho-selectivity is observed in solid state nitration to yield
