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 ...

Lithol Rubine BK is one of many dyes made from 3-hydroxy-2-naphthoic acid. Notice that the coupling occurs adjacent to the hydroxy group. 3-Hydroxy-2-naphthoic acid is a precursor to many anilides, such as Naphthol AS, which are reactive toward diazonium salts to give deeply colored azo compounds.
