Recent Advances in Rare‐Earth Metal‐Catalyzed C−H Functionalization Reactions

Abstract There has been a persistent impetus for the development of versatile C−H functionalization reactions, which represents a powerful approach to a wide variety of valuable chemical compounds. Transition metal catalyzed C−H functionalization has attracted intense interest and witnessed considerable advances in this field owing to its outstanding regioselectivity and atom‐economy. In recent years, rare‐earth (RE) metal‐based catalysts have been successfully employed in this flourished area, demonstrating unique selectivity and complementary reactivity with respect to late‐transition metal‐catalyzed C−H functionalization. The development of rare‐earth metal‐catalyzed C−H functionalization by taking the advantage of these characteristic properties is of great importance and interest. Herein, a panorama of rare‐earth metal‐catalyzed C−H functionalization during the last decade is presented.
