Oxidation and Reduction of Aromatic Rings

Abstract

Synthetic methodologies for the oxidation and reduction of the phenol rings of the calix [n ]arenes are now well established.The oxidation and reduction of these groups affect the “walls” which delimit the calix cavity and therefore substantially alter the conformation,rigidity and binding properties of the parent systems.The oxidized and reduced derivatives provide new building blocks for the construction of host systems and further extend the wide range of synthetic modifications possible for the calix skeleton.
