Resumen

This work extends recent developments relating simple models of electrophilicity index to the experimental Mayr's electrophilicity parameter [E. Chamorro, M. Duque-Noreña, P. Pérez, J. Mol. Struct. (THEOCHEM), in press]. We further explore here the usefulness of reactivity models based on density functional theory (DFT) to the study of nucleophilicity for organic compounds. The results for a series of primary and secondary amine and diaryl carbenium ions selected as donor and acceptor species, respectively, indicates that the simplified models are linearly related, within good agreements, to the experimental Mayr's nucleophilicity parameters, within the validity of the Mayr-Patz free energy equation, log k = s(N + E). These results contribute to further validate theoretical models for both electrophilicity and nucleophilicity in the establishment of general and independent scales of reactivity.
