Description

General description

2,3-Dihydroxynaphthalene is a polyhydroxy phenol. It is an aromatic dihydroxy compound having hydroxyl groups at ortho positions. Its reaction with molybdenum(VI) complexes has been reported. The asymmetric oxidative coupling polymerization of 2,3-dihydroxynaphthalene using the Cu(I)-bisoxazoline complex as catalyst has been reported to afford poly(2,3-dihydroxy-1,4-naphthylene), having a continuous 1,1′-bi-2-naphthol main chain structure. The nitrodisplacement reaction between nitrophthalodinitriles and 2,3-dihydroxynaphthalene has been investigated.

Application

2,3-Dihydroxynaphthalene may be used in the following studies:

• Construction of dinaphtho[2,1-b;2′,3′-d]furan-6-ol, via dehydration reaction in the presence of strong acid.
• As fused ring catecholate type ligand for the surface modification of nanocrystalline TiO₂ particles.
• As adsorptive and competing ligand during the chemical speciation of iron in seawater by cathodic stripping voltammetry.
• Synthesis of cyclotriphosphazene derivatives, used as non-halogen flame retardants
