Abstract

A series of oxindole derivatives substituted in the aromatic ring and their N-Me homologues has been prepared. The effects of position and nature of substituents on the IR, NMR and UV spectra have been investigated. Evidence is presented which indicates the presence of an intermolecular hydrogen bond in solutions of oxindole and certain N-unsubstituted derivatives. A relationship between Hammett's σ constant of substituents and the carbonyl ...
