An efficient synthesis of phenols via oxidative hydroxylation of arylboronic acids using (NH4)2S2O8

Abstract

A mild and efficient method for the ipso-hydroxylation of arylboronic acids to the corresponding phenols was developed using (NH4) 2S2O8 as an oxidizing agent. The reactions were performed under metal-, ligand-, and base-free conditions. © 2014 Claudia A. Contreras-Celedón et al.
