A modified Mn–PDP/HFIP catalyst that selectively oxidizes methylene C–H bonds in α,β-unsaturated carbonyl compounds is introduced; removing carboxylic acid additives and introducing HFIP suppresses undesired epoxidation with Mn-PDP, probably by promoting a more charged, chemoselective oxidation pathway.
