A Useful Classification of Organic Reactions Based on the Flux of the Electron Density
Luís R. Domingo, Mar Ríos‐Gutiérrez
Abstract
A useful classification of polar organic reactions in Forward Electron Density Flux (FEDF) and Reverse Electron Density Flux (REDF), based on the unambiguously analysis of the direction of the flux of the global electron density transfer (GEDT) at the transition state structures (TSs), has been recently proposed (RSC Adv. 2020, 10, 15394) within the Molecular Electron Density Theory. Further, non-polar reactions have been classified as Null Electron Density Flux (NEDF) (Eur. J. Org. Chem. 2020, 5938). This classification allows characterizing the nucleophilic/electrophilic species participating in polar reactions. Analysis of the electronic chemical potential m, and the electrophilicity w and nucleophilicity N indices, defined within Conceptual DFT, at the ground state (GS) of the reagents also permits to establish this classification of polar reactions.
