- 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.
