Recent Progress in the Radical Chemistry of Alkylborates and Alkylboronates

The discovery of safe and cost‐effective radical sources, exploration of novel and efficient radical reactions as well as elucidation of reaction mechanisms have been long‐standing goals for the synthetic community. Recently the utilization of alkylborates and alkylboronates as radical sources via transition metal‐catalyzed oxidative deboronation or photocatalyzed deboronative pathways has allowed the development of a wide range of innovative reactions. These methods enable chemists to forge C−C or C−X bonds for many intriguing and valuable chemical transformations. This review examines the recent significant advances in radical functionalization of alkylboronates with emphasis on both synthetic outcome and reaction mechanism. magnified image
