2. 2-Naphthol - Wikipedia

   en.wikipedia.org/wiki/2-Naphthol

   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 ...

7. 1-Nitroso-2-naphthol - Wikipedia

   en.wikipedia.org/wiki/1-Nitroso-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 ...

   Molisch test (using α-napthol) indicating a positive result (see purple ring). Molisch's test is a sensitive chemical test, named after Austrian botanist Hans Molisch, for the presence of carbohydrates, based on the dehydration of the carbohydrate by sulfuric acid or hydrochloric acid to produce an aldehyde, which condenses with two molecules of a phenol (usually α-naphthol, though other ...
