A bis(η2-cyclooctadienyl)ruthenium/PCy3/maleic anhydride system catalyzes the addition reaction of aceticacid to propargyl alcohol derivatives at 80°C to give 2-acetoxyallyl derivatives with high selectivity in high yields. The 2-acetoxyallyl carbonates prepared react with carbonucleophiles in the presence of a catalytic amount of Pd(PPh3)4 to give a series of novel polyfunctional enol esters in good
