ABSTRACT:
A process for producing halosubstituted derivatives of acetophenone from the respective halocumenes, the term "halo" as used herein, signifying chlorine or bromine, the molecule containing 1 to 3 nuclear halo substituents in the meta- and/or paraposition relative to the isopropyl group. The process comprises oxidizing the halocumene by means of air or oxygen. The oxidation is effected in the presence of a metal phthalocyanine complex as catalyst, and in a most preferred embodiment, in the co-presence of a dichlorobenzene solvent. The preferred halocumenes are p-chlorocumene and p-bromocumene.
