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

Chemical speciation of iron in seawater by cathodic stripping voltammetry with dihydroxynaphthalene.
Constant M G van den Berg
Analytical chemistry, 78(1), 156-163 (2005-12-31)
The chemical speciation of iron in seawater is determined by cathodic stripping voltammetry using 2,3-dihydroxynaphthalene (DHN) as adsorptive and competing ligand. The optimized conditions include a DHN concentration of 0.5-1 microM, seawater at its original pH of 8, and equilibration

The construction of dinaphtho[2,1-b;2',3'-d]furan-6-ol was developed via a dehydration reaction involving two molecules of 2,3-dihydroxynaphthalene in the presence of a strong acid. Starting from the dinaphthofuran, a variety of butterfly shaped derivatives were synthesized. The optical properties of these compounds

Surface modification of nanocrystalline TiO(2) particles (45 Å) with catecholate-type ligands consisting of an extended aromatic ring system, i.e., 2,3-dihydroxynaphthalene and anthrarobin, was found to alter the optical properties of the nanoparticles in a similar way to modification with catechol.
