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.
