Can acetophenone be oxidized
WebQuestion: Methylic ketones (such as acetophenone) can be oxidized through a sequence of halogenations at the CH3 adjacent to the carbonyl group, followed by a nucleophilic attack to the carbonyl group, in which the carbon with three halogens acts up as a leaving group.
