Description
Summary:An iron oxide nanocatalyst supported on a potassium exchanged zeolite-Y (Fe 2 O 3 -KY) is an efficient and reusable catalyst that promotes the selective α-H functionalization of 2-naphthols with various aromatic primary alcohols. The reaction occurs at 110 °C in dichloroethane and requires 6 h for completion. The product yields were found to vary with respect to the nature of the substituents. Benzyl alcohols with electron-donating groups gave the highest yields of up to 90%. Iron oxide supported on zeolite-Y effectively catalyzes the nucleophilic substitution of different 2-naphthols with various benzyl alcohols.
