Fluorinated Aryl Boronates as Building Blocks in Organic Synthesis

Organoboron compounds are well known building blocks for many organic reactions. However, under basic conditions, polyfluorinated aryl boronic acid derivatives suffer from instability issues that are accelerated in compounds containing an ortho-fluorine group, which result in the formation of the corresponding protodeboronation products. Therefore, a considerable amount of research has focused on novel methodologies to synthesize these valuable compounds while avoiding the protodeboronation issue. This review summarizes the latest developments in the synthesis of fluorinated aryl boronic acid derivatives and their applications in cross-coupling reactions and other transformations.

Automated summary

Organoboron compounds are essential building blocks for organic reactions, with recent focus on the synthesis of fluorinated aryl boronic acid derivatives. However, instability issues arise under basic conditions, particularly accelerated in compounds with an ortho-fluorine group, leading to protodeboronation. Research is aimed at developing novel synthesis methodologies to avoid such issues.
