The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 8-Hydroxyquinoline 1-oxide( cas:1127-45-3 ) is researched.COA of Formula: C9H7NO2.Gonzalez-Baro, Ana C.; Baran, Enrique J. published the article 《Oxovanadium(IV) and oxovanadium(V) complexes of 8-hydroxyquinoline-N-oxide》 about this compound( cas:1127-45-3 ) in Journal of Coordination Chemistry. Keywords: vanadyl hydroxyquinoline oxide hydroxide complex preparation; oxovanadium hydroxyquinoline oxide hydroxide complex preparation. Let’s learn more about this compound (cas:1127-45-3).
The oxovanadium(IV) and oxovanadium(V) complexes, VO(NOQ)2 and VO(NOQ)2OH, resp., containing the N-oxide of 8-hydroxyquinoline (NOQH) as a ligand were synthesized and characterized by elemental anal., IR, Raman and electronic spectroscopy. The vibrational spectra are discussed in detail and a full assignment in the spectral range between 1700-200 cm-1 is proposed. Some comparisons with related species are made.
