Abstract
Molecular charge-transfer (CT) complexes of some oxazolone derivatives with sigma-electron acceptor iodine have been investigated spectrophotometrically in CH2Cl2 at 20 degrees C. Stability constants of the CT complexes formed were computed and discussed in terms of the donor molecular structure and solvent polarity. The thermodynamic parameters of complex formation were determined and discussed. The solid CT complexes have been synthesized and characterized. It was deduced that the complexes formed are of strong n-sigma kind.
