The nucleophilicity equalization principle and new algorithms for the evaluation of molecular nucleophilicity

In this work, we have attempted to explore whether the nucleophilicity equalization principle can be conceived analogous to the well-established electronegativity, hardness, and electrophilicity equalization principle. Based on our new definitions of hardness and electronegativity and relying upon the geometric mean principle we proposed a new electronic structure principle, namely the nucleophilicity equalization principle. This approach provides a unified and useful procedure to calculate the nucleophilicity of molecules and groups assuming that nucleophilicity equalization principle is operative and justifiably valid. The results shown here indicate a close resemblance between theory and experiment. (C) 2016 Elsevier B.V. All rights reserved.
