Oxidation of acetophenone mechanism

WebSep 10, 2013 · The selective oxidation of ethylbenzene and cyclohexene to acetophenone and 2-cyclohexene-1-one using N-hydroxyphthalimide (NHPI) under oxygen atmosphere in the presence of an SiO 2 /Al 2 O 3 -supported cobalt catalyst occurs with conversions of 83 and 75% and selectivities of 99%. WebThe manganic acetate-catalyzed autoxidation (110 °C, 1 atm of oxygen) of acetophenone (<0.7 M) in CH 3 COOD as well as of acetophenone-ω-d 3 in CH 3 COOH proceed at the same rates as the H D exchange under the same conditions but in the absence of oxygen. In both oxidation reactions, the unoxidized ketones retain their isotopic compositions.
