Abstract: In a search for intramolecular concerted general acid, general base and general acid, nucleophilic catalysis, the hydrolyses of four systems of esters were examined:(1) 6- and 8-quinolyl hydrogen glutarates and succinates;(2) 0-andg-carboxyphenyl succinates;(3) methyl y-and P-resorcylates; and (4) phenyl esters of 4-and 6-substituted salicylates. Bell- shaped pH-kobsd profiles interpretable as resulting from bifunctional catalysis were ...
