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 ...
