Recent advances in Cu-catalyzed C(sp 3 )-Si and C(sp 3 )-B bond formation

Numerous reactions generating C-Si and C-B bonds are in focus owing to the importance of incorporating silicon or boron into new or existing drugs, in addition to their use as building blocks in cross-coupling reactions en route to various targets of both natural and unnatural origins. In this review, recent protocols relying on copper-catalyzed sp carbon-silicon and carbon-boron bond-forming reactions are discussed.
