Phosphorus-Directed C-H Borylation

Phosphorus-containing compounds have a long history of utility in a broad range of fields, including agricultural, pharmaceutical, and metal-mediated reactions. In recent decades, numerous methods have been developed to streamline the synthesis of organophosphorus reagents based on these numerous applications. This review focuses upon the recent development of phosphorus(III)- and phosphorus(V)-directed C-H borylation reactions. This transformation has evolved significantly in the past two years, resulting in several new methods that provide access to organic substrates containing both phosphorus and boron. Further functionalization of the carbon-boron bond to provide functionalized organophosphorus products is discussed.
