Abstract

Abstract : a N and a P of β-phosphorylated 5-membered ring nitroxides are sensitive to the polarity/polarisability π*, the structuredness of the solvent c, and to the hydrogen bond donating α properties of the solvent. Abstract : Recently, we published the titration of water in organic solvents and conversely using this family of nitroxides ( Org. Biomol. Chem. 2015 ASAP). In this article, we show that the a β, P of persistent cyclic β-phosphorylated nitroxides decreases with the normalized polarity Reichardt's constant E NT. Koppel–Palm and Kalmet–Abboud–Taft relationships were applied to get a deeper insight into the effects influencing a N and a β, P : polarity/polarizability, hydrogen bond donor property, and structuredness of the cybotactic region.
