Quantum chemical calculations, NMR studies and experimental evidences demonstrated the presence of equilibriums of at least four different conformations: π-stacked and face-to-edge, each of them in an s-cis/s-trans conformation. The results show that the stabilization produced by the π–π interaction makes the π-stacked conformation predominant in solution and this stabilization is slightly affected by the electron density of the aromatic counterpart.application/pdf1616–1623engopenAccessBiomassπ-stacking interactionAcrylic EstersAsymmetric SynthesisConformational EquilibriumarticleCorne, ValeriaSarotti, Ariel MarceloRamirez de Arellano, CarmenSpanevello, Rolando ÁngelSuárez, Alejandra GracielaUniversidad Nacional de RosarioAttribution 4.0 International (CC BY 4.0)
