Abstract
Abstract A process for preparing allylic esters of carboxylic acids and allylic alcohols which comprises reacting a mixture of a lower alkyl carboxylate ester, water, and the corresponding carboxylic acid and alcohol with an olefin having an allylic carbon-hydrogen bond and oxygen in the presence of a catalyst system comprising an oxidation catalyst and an acidic co-catalyst.
