Descrizione generale

2-Naphthol undergoes three-component one-pot condensation reaction with ureas/amides and aldehydes catalyzed by sulfamic acid under ultrasound irradiation to give 1-amidoalkyl-2-naphthols. Anodic oxidation of 2-naphthol in acidic media has been investigated at a synthetic boron-doped diamond thin film electrode using cyclic voltammetry and bulk electrolysis.
