Advances in the development of catalytic tethering directing groups for C–H functionalization reactions

Transition metal-catalyzed C–H bond insertion is one of the most straightforward strategies to introduce functionalities within a hydrocarbon microenvironment. For the past two decades, selective activation and functionalization of certain inert C–H bonds have been made possible with the help of directing groups (DGs). Despite the enormous advances in the field, an overwhelming majority of systems require two extra steps from their simple precursors: installation and removal of the DGs. Recently, traceless and multitasking groups were invented as a partial solution to DG release. However, installation remains largely unsolved. Ideally, a transient, catalytic DG would circumvent this problem and increase the stepand atom-economy of C–H functionalization processes. In this review, we summarize the recent development of the transient tethering strategy for C–H activation reactions.
