Abstract
This invention provides process embodiments for acyloxylation of C.sub.1 -C.sub.4 alkylaromatic compounds to produce alpha-acyloxy C.sub.1 -C.sub.4 alkyl-substituted aromatic compounds, utilizing a palladium-tin catalyst which exhibits efficient oxidation selectivity and oxidation rate stability. Toluene is acetoxylated to benzyl acetate and benzylidene diacetate.
