Anodic Formation of Aryl Mesylates through Dehydrogenative Coupling Reaction

Abstract

AbstractThe first direct anodic mesylation of aromatic substrates was established. The installation of the oxygen‐carbon bond was achieved through a dehydrogenative coupling reaction, which works with naphthalene in preparative attractive yields, and this protocol can be applied to a range of other aromatic substrates. The electroconversion is conducted at carbon anodes in a divided cell. The constant current conditions allow electrolysis with a simple electronic periphery. The results are in full accordance with cyclic voltammetry studies, providing a consistent picture.
