The Bigger Picture
Transition-metal-catalyzed C–H activation enables the use of easily accessible feedstocks for molecular syntheses, which holds great potential for sustainable syntheses. These C–H functionalizations are largely achieved by proximity-induced reactivity, exploiting strongly coordinating directing groups to ensure the required positional selectivity in intermolecular transformations. Since the installation and removal of the strongly coordinating directing groups calls for additional reaction steps, undesired waste is formed, which compromises the overall step- and atom-economical nature of C–H activation technology. Further, performing C–H activations with weakly coordinating functional groups continues to represent a formidable challenge. In this review,
