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 ...

Naphthalene-2-sulfonic acid is an organic compound with the formula C 10 H 7 SO 3 H. A colorless, water-soluble solid, it is often available as the mono- and trihydrates C 10 H 7 SO 3 H . 2H 2 O. It is one of two mono sulfonic acids of naphthalene , the other being naphthalene-1-sulfonic acid .
The reagent removes pairs of H atoms from organic molecules. The stoichiometry of its action is illustrated by the conversion of tetralin to naphthalene: 2 C 6 Cl 2 (CN) 2 O 2 + C 10 H 12 → 2 C 6 Cl 2 (CN) 2 (OH) 2 + C 10 H 8. The resulting hydroquinone is poorly soluble in typical reaction solvents (dioxane, benzene, alkanes), which ...

c 10 h 7-2-oh + nh 3 ⇌ c 10 h 7-2-nh 2 + h 2 o The French chemist Robert Lepetit was the first to discover the reaction in 1898. The German chemist Hans Theodor Bucherer (1869–1949) discovered (independent from Lepetit) its reversibility and its potential especially in industrial chemistry.
