摘要：

A model based on simple Hückel MO theory is applied to the ring-openings of several cyclobutene derivatives and their benzo- and bis-methylene-analogs. The calculated changes in activation enthalpy upon benzannelation and bismethylenation are found to be in qualitative accord with experimental results. Application of the model to Dewar benzene and bicyclo[4.2.0]octa-2,4,7-triene ring-opening is discussed. © 1979.
