Abstract

The equilibrium constants, the associated free energies for the equilibria, and the free energies of activation for the isomerization process of a series of 1- and 2-N,N-dialkylaminoalkyl)benzotriazoles of types (8)-(11) were calculated from the variable temperature 1H-nmr spectra. Trends in the magnitudes of these energies and equilibrium constants are correlated with the molecular structure.
