Transmission of electronic effects by the oxiran ring. Ionization constants of meta- and para-substituted 2,3-epoxy-3-phenylpropionic acids in 50% ethanol
Abstract
The ionization constants of meta- and para-substituted 2,3-epoxy-3-phenyl propionic acids have been measured in 50% ethanol. The results show that the oxiran ring transmits conjugation slightly better than the cyclopropane ring.
