Reasons for structure-acid resistance correlation in series of substituted phenylpenicillins

The kinetics of acid hydrolysis of phenylpenicillins substituted in the benzene ring were studied at pH 3.0 and temperatures of 20, 25, and 30°C. A Hammett correlation analysis of the reaction was performed.
