, p. 227 - 231 (2009)
A rapid and efficient method is described for the selective synthesis of enol esters via the microwave-accelerated addition of carboxylic acids to terminal alkynes. The method employs the readily available [RuCl 2(p-cymene)(PPh3)] complex as catalyst without the need of bases, and reactions are complete in 20 min.

An efficient and highly selective synthesis of vinyl esters was developed that employed carboxylic acids and terminal alkynes as reagents, and novel tethered (η1:η6-phosphanoarene)ruthenium complexes as catalyst precursors. With thes

Carboxylic acids react with alkynes in the presence of a catalytic amount of bis(ν5-cyclooctadienyl)ruthenium/trialkylphosphine/maleic anhydride in toluene at 60-80 deg.C to give enol esters having a terminal methylene group in good to excellent yields with high regioselectivity.The deuterium distributions in the products of the reaction of acetic acid-d with 1-hexyne and ethyl propargyl carbonate were examined.Kinetic measurments revealed that the rate has first-order dependence on carboxylic acid, alkyne, and the initial concentration of the ruthenium catalyst.
