Abstract
Abstract: Rate constants have been obtained for hydrolysis of 2-pyridylmethyl hydrogen phthalate, an ester with a poor leaving group, at 90 OC in the pH range 6-1 1. The pH-rate constant profile shows hydroxide ion catalysis at high pH and a plateau due to nucleophilic carboxyl group participation. Divalent metal ions (NiZ+, Cozt, ZnZ+) exert a large catalytic effect, although binding to the substrate is weak. Saturation effects were not observed ...
