Recent Advances in the Hydroxylation of Boronic Acids

Abstract

Hydroxylated compounds represent a significant and diverse class of substances in the field of chemistry. These compounds play critical roles in various chemical reactions and are essential components in numerous industrial applications. Recent years have witnessed remarkable advancements in the synthesis of hydroxylated compounds, especially those derived from boronic acids. The synthesis of hydroxylated compounds from boronic acids typically involves the utilization of various types of catalysts, which are essential for enhancing reaction rates and selectivity, including metal catalysts such as CuFe₂O₄, Cu@C₃N₄, AgNPs, and Ti0.97Ni0.3O1.97, as well as non-metal catalysts like polycaprolactone (PCL), TFB-BMTH COF materials, C70, and graphene oxide (GO). These catalytic reactions often require the addition of oxidants such as hydrogen peroxide (H₂O₂) or molecular oxygen, which serve as critical reagents in the hydroxylation process. In certain cases, organic bases act as electron donors to propel the reaction. Furthermore, some studies have reported oxidative hydroxylation reactions that are catalyst-free.This review aims to summarize the recent advancements and breakthroughs in the synthesis of hydroxylated compounds from boronic acids, with a particular focus on research conducted from 2014 to 2024.
