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-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]

3-Hydroxy-2-naphthoic acid is an organic compound with the formula C 10 H 6 (OH)(CO 2 H). It is one of the several hydroxynaphthoic acids. It is a precursor to some azo dyes and pigments. It is prepared by carboxylation of 2-naphthol by the Kolbe–Schmitt reaction. [1]
2-Methoxynaphthalene, also called β-naphthol methyl ether or yara yara, [2] is a stabilizer found in gunpowder, particularly smokeless gunpowders. It is soluble in alcohol , and insoluble in water and dipropylene glycol .
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 .
