Abstract

By means of the joint use of electron localization function and Thom's catastrophe theory, a theoretical analysis of the energy profile for the hetero-Diels- Alder reaction of 4-methoxy-1,2- benzoquinone and methoxyethylene has been carried out, as presented on page 2400 by Patricio González-Navarrete and colleagues. This analysis permits finding a relationship between the electron localization function topology and the evolution of the bond breaking/forming processes and electron pair rearrangements through the reaction progress in terms of the different ways of pairing up the electrons.
