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]

Traditionally, 2-naphthol is produced by a two-step process that begins with the sulfonation of naphthalene in sulfuric acid: [2] C 10 H 8 + H 2 SO 4 → C 10 H 7 SO 3 H + H 2 O. The sulfonic acid group is then cleaved in molten sodium hydroxide: C 10 H 7 (SO 3 H) + 3 NaOH → C 10 H 7 ONa + Na 2 SO 3 + 2 H 2 O. Neutralization of the product ...

1-Naphthalenethiol is an organosulfur compound with the formula C 10 H 7 SH. It is a white solid. It is a white solid. It is one of two mono thiols of naphthalene , the other being 2-naphthalenethiol .
2-Naphthoic acid is an organic compound of the formula C 10 H 7 CO 2 H. It is one of two isomeric carboxylic acid derivatives of naphthalene , the other one being 1-naphthoic acid . It can be prepared by carboxylation of 1-chloronaphthalene .
2-Naphthylamine or 2-aminonaphthalene is one of two isomeric aminonaphthalenes, compounds with the formula C 10 H 7 NH 2. It is a colorless solid, but samples take on a reddish color in air because of oxidation. It was formerly used to make azo dyes, but it is a known carcinogen and has largely been replaced by less toxic compounds. [2]
1-Naphthol, or α-naphthol, is an organic compound with the formula C 10 H 7 OH.It is a fluorescent white solid. 1-Naphthol differs from its isomer 2-naphthol by the location of the hydroxyl group on the naphthalene ring.
