1-Naphthol is a precursor to a variety of insecticides including carbaryl and pharmaceuticals including nadolol [8] [9] as well as for the antidepressant sertraline [10] and the anti-protozoan therapeutic atovaquone. [11] It undergoes azo coupling to give various azo dyes, but these are generally less useful than those derived from 2-naphthol ...

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 ...
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.
