    State of the Art of the Bonding Changes along the Diels-Alder Reaction between Butadiene and Ethylene: Refuting the Pericyclic Mechanism

    Author(s): Domingo LRDomingo LR

    Bonding changes along the Diels-Alder reaction between butadiene 1 and ethylene 2 and related non-polar Diels- Alder reactions have been analysed using the Bonding Evolution Theory (BET). The Electron Localization Function (ELF) analysis of these synchronous single bond-formation processes indicates that C-C bond formation takes place by the C-to-C coupling of two pseudoradical centers formed along the reaction. The present study permits the establishment of two significant findings: i) the breaking of the C=C double bonds in butadiene 1 and ethylene 2 and the formation of the new C-C single bonds in cycloadduct are non-concerted due to the changed in electron density required for the formation of the pseudoradical centers, and ii) the symmetric changes in electron density along these cycloadditions do not have a cyclic movement. These behaviours, which are opposite to the “conc.. Read More»
