Abstract
UHF/AM1 molecular orbital method has been employed to study the therma l Diels-Alder reaction of ethene with cyclohexa-1,3-diene, The results showed that this reaction is exothermal, and it has two competitive r outes; the activation energy of the concerted process is 112.667 kJ/mo l, and that of the rate-determining step of the biradical pathway is 7 8.406 kJ/mol, the biradical process has lower activation energy than t he concerted one.
