The kinetics of the oxidative acetoxylation of propylene to allyl acetate in solutions of the clusters Pd/sub 561/Phen/sub 60/(OAc)/sub 180/ and Pd/sub 561/Phen/sub 80/(PF/sub 6/) have been studied by gas-liquid chromatography over the range 40-90/degree/C. It has been established that the rate of reaction is proportional to the concentrations of propylene and the clusters in solution and its dependence on the concentrations of O/sub 2/ and acetic acid is represented by a Michaelis type of equation. For high partial O/sub 2/ pressures inhibition of the reaction by oxygen is observed. A mechanism is proposed for the reaction, according to which the cleavage of the C-H bond in the coordinated olefin molecule to form an allyl complex takes place at the limiting stage.
