Abstract: The kinetics of transformation of charge transfer complexes of anilines-DDQ has been studied spectrophotometrically by stabilising the complexes in CCl4, a low polar solvent, at low temperatures and under low donor concentrations. The decay of CT complexes has been followed by decrease in the absorbance of CT band and it has been found to follow pseudo first order kinetics. The stability constants of the complexes have been determined from kinetic studies, using the method described by Rappoport. A linear relationship is observed between logarithmic functions of stability constants and Hammett σ constants. Thermodynamic parameters of the complexes have been evaluated from temperature variation of stability constant.
