Copper-boryl mediated organic synthesis

Abstract

The diverse applications of copper-catalyzed borylation, which has become an essential strategy in modern synthetic organic chemistry, are reviewed and illustrated.

Abstract

Organoboron compounds are valuable synthetic intermediates that find application in a diverse variety of processes including both C–X and C–C bond-forming transformations. This has been achieved by using a variety of boron derivatives. Of these, boronate esters are probably the most versatile and, reflecting this, methods for the generation of boronate esters are of considerable current interest. Given the mild reaction conditions, good functional group tolerance, and low cost of the metal catalyst, the use of copper-boryl reagents is particularly attractive. In this review, methodologies in copper-boryl chemistry are discussed and the many different transformations possible are surveyed.
