The Journal of Physical Chemistry A, 2009
The concept of net electrophilicity (electroaccepting power relative to electrodonating power) is introduced. It provides expected trends in most cases. A net electrophilicity scale is presented. Various reactivity descriptors for 32 molecules are calculated at the B3LYP/6-311+G(d) level of theory.

Electrophilicity index revisited
Journal of Computational Chemistry, 2022AbstractThis review aims to be a comprehensive, authoritative, critical, and accessible review of general interest to the chemistry community; because the electrophilicity index is a very useful global reactivity descriptor defined within a conceptual density functional theory framework.

Thermodynamic electrophilicity
The Journal of Chemical Physics, 2017We revisit the electrophilicity index proposed by Parr et al., with special emphasis on the working equations used to calculate this descriptor. We show that the standard way to obtain this reactivity index (using the conceptual density functional theory formalism) leads to several issues. In this contribution, we propose to overcome these difficulties

Stereoselective Electrophilic Cyclization
The Chemical Record, 2015AbstractElectrophilic cyclizations of unactivated alkenes play highly important roles in the synthesis of useful building blocks. This account describes our contributions to the rational design of monofunctionalized chiral Lewis base catalysts for enantioselective iodo‐ and protocyclizations.

Electrophilic Amination with Nitroarenes
Angewandte Chemie International Edition, 2017AbstractAn exceptionally general electrophilic amination, which directly transforms commercially available nitroarenes into alkylated aromatic aminoboranes with zinc organyl compounds was developed. The reaction starts with a two‐step partial reduction of the nitro group to a nitrenoid, which is used in situ as the electrophilic amination reagent.

Electrophilic Reactivities of Azodicarboxylates
Chemistry – A European Journal, 2010AbstractThe kinetics of the reactions of the azodicarboxylates 1 with the enamines 2 have been studied in CH3CN at 20 °C. The reactions follow a second‐order rate law and can be described by the linear free energy relationship log k2(20 °C)=s(N+E) (E=electrophilicity parameter, N=nucleophilicity parameter, and s=nucleophile‐specific slope parameter ...
