The ability of the hydrosoluble ruthenium(II) complexes [RuCl2(η6-arene)(PTA)] 3a–d, [RuCl2(η6-arene)(PTA-Bn)] 4a–d, [RuCl2(η6-arene)(DAPTA)] 5a–d, [RuCl2(η6-arene)(TPPMS)] 6a–d (arene = C6H6, p-cymene, 1,3,5-C6H3Me3, C6Me6) to promote the atom-economic formation of β-oxo esters, by addition of carboxylic acids to terminal propargylic alcohols in water has been explored. Scope, limitations and catalyst
