The endo/exo stereoselectivity of the Diels-Alder cycloaddition between cyclopentadiene and 3-crotonoyl-2-oxazolidinone catalysed by Et 2 AlCl is temperature-and solvent-dependent. Eyring plots of ln(endo/exo) versus 1/T show different inversion temperatures (T inv ) depending on the reaction solven
## Abstract __Herein we demonstrate that an external electric field (EEF) acts as an accessory catalyst/inhibitor for Diels–Alder (DA) reactions. When the EEF is oriented along the “reaction axis” (the coordinate of approach of the reactants in the reaction path), the barrier of the DA reactions is
