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] Bromination [7] and alkylations proceed with similar regiochemistry. [8] Ring-opening reactions have been documented. [9] Carbonation of 2-naphthol gives 2-hydroxy-1 ...
2-Naphthalenethiol is prepared from 2-naphthol by the Newman–Kwart rearrangement starting from a thiocarbamate. [1] It undergoes lithiation at the 1 and 3-position. [2] [3] It can be used as a flavouring agent and has been described as having an “artichoke”, “meaty” and “creamy” taste”. [4] [5]
With NaOH, converts to 5-amino-1-naphthol ("purpurol"). 1-Aminonaphthalene-6-sulfonic acid: 119-79-9: 1,6-Cleve’s acid (named after swedish chemist Per Teodor Cleve) sulfonation of 1-aminonaphthalene: 1-Aminonaphthalene-7-sulfonic acid: 119-28-8: 1,7-Cleve’s acid: by-product in production of 1,6-Cleve’s acid, precursor to C.I. Acid Black ...

The reaction is used to convert 1,7-dihydroxynaphthalene into 7-amino-1-naphthol and 1-aminonaphthalene-4-sulfonic acid into 1-hydroxynaphthalene-4-sulfonic acid. It is also useful for transamination reactions of 2-aminonaphthalenes .
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 ...

1,1 ′-Bi-2-naphthol (BINOL) is an organic compound that is often used as a ligand for transition-metal catalysed asymmetric synthesis. BINOL has axial chirality and the two enantiomers can be readily separated and are stable toward racemisation .
