Abstract
A catalytic homogeneous liquid phase process for effecting the acyloxylation of toluene to produce the corresponding benzylic ester. The catalyst system comprises Pd(II) and Pb(II) values wherein the palladous element component is associated with a catalytic amount of a tertiary phosphine as a complexed ligand. The indicated catalyst system uniquely facilitates the advantageous use of normally immiscible carboxylic acid reactants for carrying out the underlying benzylic oxidation reaction.
