Kinetic Studies in the Oxidation of 2-aryl-3-Hydroxychromenones Using Sodium Hypochlorite (NaOCl) as an Oxidant

It has been reported that sodium hypochlorite (NaOCl) was used to oxidise 3-hydroxy flavone (3-HF) and 3-hydroxy-2-(thiophene-2-yl)-4H-chromen-4-one (THC). IR, 1H-NMR, and ESI-MS spectroscopic techniques were used to identify 3-hydroxy-2,3-dimethoxy-2-phenylchroman-4-one (1a) as the product of 3-HF in methanol (MeOH) as the
