, p. 217 - 224 (2007/10/02)
By comparison of the heats of hydrogenation of fixed norcaradienes with analogous cyclobutane derivatives and from the difference of experimental heats of formation with values calculated by force-field methods the homoaromatic stabilization of norcaradienes and cycloheptatrienes are calculated and compared with the equilibrium position of the respective valence isomers.Key Words: Homoaromaticity / Resonance energy / Calculations, force-field / Heats of hydrogenation
