How does the global electron density transfer diminish activation energies in polar cycloaddition reactions? A Molecular Electron Density Theory study

Tetrahedron, 2017
Abstract The key role of the Global Electron Density Transfer (GEDT) in polar cycloaddition reactions is analysed within the Molecular Electron Density Theory (MEDT) using Density Functional Theory (DFT) calculations at the MPWB1K/6-311G(d) computational level. A comparative MEDT study of the non-polar Diels-Alder reaction between cyclopentadiene (Cp)

Polarity‑controlled Lewis acid catalysis in the Diels–Alder reaction of cyclopentadiene and acrolein: a DFT and global electron density transfer (GEDT) analysis of BF3 and AlCl3

Journal of Molecular Modeling
Lewis acid catalysis plays a central role in controlling the reactivity and selectivity of pericyclic reactions by polarizing the reacting fragments and stabilizing the corresponding transition states. In this work, the endo reaction pathway is examined in the absence of catalysis and in the presence of the Lewis acids BF3 and AlCl3 to clarify how ...
