WebThe study and analysis of the changes on the electron localisation function topology along a given reaction path reveals fluxes of electron density, allowing to unambiguously identify the main chemical events happening along the chemical reactions. WebHydrogen bonding between the 1,3-dipole and acetylene is generally stronger, which leads to higher reaction barriers in the acetylene case. Elementary differences are found with regard to charge transfer, charge polarization, rehybridization, and bond formation of the two dipolarophiles, which explain their different reaction energies.
