Abstract
Olefins, such as propylene, are allylically oxidized to corresponding unsaturated aldehydes and carboxylic acids, such as acrolein and acrylic acid, by contacting the olefin with molecular oxygen at allylic oxidation conditions in the presence of a trifluoroalkyl sulfonate or phosphonate catalyst, such as a catalyst formed by the reaction of vanadyl oxide and trifluoromethyl sulfonate.
