WebThe kinetics of oxidation of substituted styryl phenyl ketones and of substituted Styrylmethyl ketones by pyridinium chlorochromate (PCC) have been studied in 90% acetic acid-10% water (v/v) containing perhloric acid and NaCIO 4, at 30°, 40°, 50° and 60°e. The two reactions are first order each in ketones and PCe. WebCompound 4 underwent a base-catalyzed breakdown due to the instability of its enolate form which resulted in the formation of a pyridine-4-aldoxime and phenyl vinyl ketone. Ionization constants of 3 and 4 keto-forms were estimated as the lowest possible pKa values of 12, while the pKa value of pyridinium aldoxime group of 4 was found to be 8.51 ± 0.04.
