Boronic acids. Hammett analysis of 2,6-diarylphenylboronic acids reveals that their Lewisacidity remains unchanged upon the introduction of EWG/EDG at the distant para position of the flanking aromatic rings. Structural and computational studies demonstrate that polar-π interactions and solvation effects contribute to the stabilization of boronic acids and boronate forms by aromatic rings, providing
