Relationship between the electrophilicity and σ<inf>p</inf> Hammett constant in Baeyer-Villiger reactions

Abstract:

The Baeyer-Villiger oxidation of some aldehydes and ketones has been revised by using the electrophilicity as a descriptor of reactivity. The global electrophilicity index evaluated at the ground state of a series of aromatic aldehydes and ketones shows a linear relationship with the σp Hammett substituent constants. The theoretical scale correctly accounts for the electrophilic activation/deactivation effects promoted by electron withdrawing and electron releasing substituents in these molecules. © 2008 Elsevier B.V.
