    • Phenylnaphthol derivatives represented by the following general formula (1),

      wherein, R 1 to R 3 are hydrogen atoms, alkyl groups or aryl groups, and R 2 and R 3 may be bonded together to form an aliphatic hydrocarbon ring or a heterocyclic ring, a and b are, respectively, integers of 0 to 4, R 4 and R 5 are hydroxyl groups, alkyl groups, haloalkyl groups, cycloalkyl groups, alkoxy groups, amino groups, heterocyclic groups having a nitrogen atom as a hetero atom and are bonded together via the nitrogen atom, cyano groups, nitro groups, formyl groups, hydroxycarbonyl groups, alkylcarbonyl groups, alkoxycarbonyl groups, halogen atoms, aralkylgroups, aralkoxy groups, aryloxy groups, aryl groups, heteroaryl groups bonded together via a carbon atom in the ring, alkylthio groups, cycloalkylthio groups, arylthio groups or heteroarylthio groups, and if R 4 or R 5 are present in a plural number, the plurality of R 4 or the plurality of R 5 may be the same or different, or 2 R 4 s or 2 R 5 s may be bonded together to form an alicyclic hydrocarbon ring or a heterocyclic ring. The compounds are useful as intermediate products for the synthesis of, for example, photochromic compounds.
