DESARROLLO DE LOS ÍNDICES DE PODER ELECTROFÍLICO Y NUCLEOFÍLICO DENTRO DEL MARCO CONCEPTUAL DE LA TEORÍA DEL FUNCIONAL DE LA DENSIDAD

In this work, the electrophilic and nucleophilic power indices were developed in the basis of canonical and grand canonical ensembles respectively, also local versions of these indices has been derived in analogy to philicity concept by Chattaraj. It can be observed that local electrophilic power and local nucleophilic power contain a third order response function, namely the hyperhardness, which recently has been considered for its chemical relevance. Also, the reactivity indices proposed here were tested by predicting the relative reactivity of molecules within three series of compounds (butyl-lithium isomers, carbonyl compounds, and aromatic motifs). In general, the global reactivity indices were in agreement with the experimental observations, while local versions shown a good representation of the site reactivity of the majority of studied system giving better results in some of cases if matched with both the Fukui functions and dual descriptor.
