Interests: theoretical organic chemistry; molecular electron density theory; density functional theory; conceptual DFT reactivity indices; electron localisation function; quantum theory of atoms in molecules, bonding evolution theory; non-covalent Interactions; molecular mechanisms; reactivity; selectivity
In order to emphasise the idea that the capability for changes in electron density, and not molecular orbital interactions, are responsible for the molecular reactivity in organic chemistry, a new reactivity theory, named Molecular Electron Density Theory (MEDT), is being proposed. Within the MEDT, the molecular reactivity in organic chemistry is studied using quantum chemical tools based on the analysis of the electron density such as the conceptual Density Functional Theory (DFT) reactivity indices, the topological analysis of the Electron Localisation Function (ELF) of the electron density focused on the progress of the bonding changes along the reaction path and the non-covalent interactions (NCI) analysis at the transition state structures (TSs) in order to understand experimental outcomes.
Conceptual DFT—a branch of DFT developed in the last quarter of the last century—provided rigorous theoretical tools to justify and deeply understand chemical concepts (such as electronegativity and the HSAB principle) which have been known and used by chemists for many years. In this framework, global and local reactivity indices were also defined, usually as derivatives of the molecular electron density and energy.
Since the beginning of this century, the analysis of the global DFT reactivity indices, such as the electronic chemical potential µ, the chemical hardness η, the electrophilicity ω and the nucleophilicity N, and the analysis of the local indices, such as local softness and Parr functions, have proved to be a powerful tool in the study of reactivity and selectivity (regio- and chemoselectivity) in polar organic reactions.
In this Special Issue, several studies in which the analysis of the DFT reactivity indices of the reagents involved in organic reactions provides meaningful information are presented, thus reflecting the broad range of applications of DFT indices in the study of organic chemical reactivity.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
