Abstract
Hoppé and Prue1, during an investigation of kinetic salt effects in the hydrolysis of the half esters of dicarboxylic acids, found that calcium(II), barium(II) and hexammino cobalt (III) ions had a slight catalytic effect on the hydrolysis of potassium ethyl oxalate. The reaction was examined using equimolar quantities of sodium hydroxide and ester (0.01 M) in the presence of the various metal salts, conditions unsuitable for investigations of the effect of transition metal ions on the reaction. We wish to report catalysis by copper (II) and nickel (II) ions in this reaction.
