The activation and functionalization of carbon-hydrogen (C-H) bonds represent a fundamental challenge in modern organic chemistry, particularly due to the inherent stability and prevalence of these bonds in organic molecules. These bonds, which typically exhibit bond energies ranging from 90 to 110 kcal/mol, constitute the majority of bonds in organic chemicals. Therefore, their selective functionalization is essential for advancing the synthesis of complex molecules like pharmaceuticals, polymers, or agrochemicals. Advancements in organometallic catalysis have facilitated significant progress in this area through C-H activation, transforming these inert bonds into reactive carbon-transition metal (C-M) bonds. Subsequent transformations of these complexes enable the formation of an array of new functional groups, such as carboncarbon and carbon-heteroatom bonds, underpinning a plethora of synthetic applications.
