Abstract
Abstract 4-Imidazoleacetate efficiently catalyzes the cleavage of bis(2,4-dinitrophenyl) hydrogenphosphate and bis(4-nitrophenyl) hydrogenphosphate (1600 and 15000 fold acceleration at pH 8.0 at 1.0 mol dm−3). The effective catalysis is ascribed to the intramolecular cooperation of the imidazolyl and the carboxylate residues.
