Selectivity-reactivity correlations are shown to support a biradical pathway for the gas phase thermal Diels-Alder reactions of cyclohexa-1,3-diene with substituted ethenes except for those involving a carbonyl group. \* All cycloadducts are considered as endo or ex0 according to the orientation of
