Despite an extensive literature, controversy about the Diels-Alder reaction mechanism still exists. For the thermal dimerization of 1,3-butadiene, for example, a concerted one-step [I] or two-stage [2] mechanism, a mixture of orbital symmetry allowed and forbidden cycloadditions 131, as well as a tw
