Cover Feature: π‐Conjugation as a Direct Estimate of Lewis Acidity (Chem. Asian J. 3/2025)

The cover shows how the relative Lewis acidity of a given Lewis acid can be directly estimated by computing the pi-conjugative strength in trans-crotonaldehyde-Lewis acid complexes (the species used in the well-known Childs’ Lewis acidity scale). The (easy-to-compute) values given by the Energy Decomposition Analysis - Natural Orbital for Chemical Valence (EDA-NOCV) approach constitute a reliable and alternative Lewis acidity scale which may even be used to predict the acidity of hitherto unknown Lewis acids. More details can be found in article number e202401212 by Daniel González-Pinardo and Israel Fernández.
