Reaction Steps

The autoclave was charged with 0.3 gms of palladium chloride, 5 gms o-trifluoromethylphenyldiphenylphosphine, 10 mls of methanol and 50 ml of p-dioxane. After flushing with nitrogen, the autoclave was pressurized with carbon monoxide to 800 psig and heated to 120 degrees C. with stirring. 10 gms of liquid propylene was added and the reaction continued at 120° C. and 100 psig for 3 hours. The autoclave was then cooled and the reaction fluid analyzed by gas chromatography. A methyl isobutyrate:methyl n-butyrate ratio of 7.1:1 was obtained.
