2-Naphthol converts to 2-naphthalenethiol by reaction with dimethylthiocarbamoyl chloride via the Newman–Kwart rearrangement. [4] The OH→Br conversion has been described. [5] Electrophilic attack occurs characteristically at the 1-position as indicated by nitrosylation to give 1-nitroso-2-naphthol. [6]

2 in the presence of vanadium pentoxide as catalyst gives phthalic anhydride: C 10 H 8 + 4.5 O 2 → C 6 H 4 (CO) 2 O + 2 CO 2 + 2 H 2 O. This reaction is the basis of the main use of naphthalene. Oxidation can also be effected using conventional stoichiometric chromate or permanganate reagents.
1-Nitroso-2-naphthol can be prepared by treatment of 2-naphthol with nitrous acid: [3] C 10 H 7 OH + HNO 2 → C 10 H 6 (NO)OH + H 2 O. Its conjugate base forms deeply colored complexes with iron(II) and cobalt(II), complexes [M(C 10 H 6 (NO)O) 3] 2-. [4] The deep colors of these complexes results from the delocalized bonding within each five ...

2-Naphthol can also be produced by a method analogous to the cumene process. [11] 3-Chlorophenol, which does not arise by chlorination of phenol, can be produced by cumene process beginning with the alkylation of chlorobenzene with propylene. [12] Cresols are produced from isopropyltoluene. [13]
