Abstract
AbstractDirect synthesis of previously undescribed 5‐aryl‐substituted pyrrol‐2‐one derivatives containing a butadienetricarbonitrile (BDTC) acceptor was carried out. The kinetics of their reversible interaction with morpholine accompanied with high‐contrast color changes in acetonitrile solution was studied for the first time. It was found that the electronic effects of substituents in aromatic ring had a direct effect on the reaction rate and extent, that was supported by the observed linearity between the estimated equilibrium constants and the electrophilic Hammett constants.
