Rollover Cyclometalation as a Valuable Tool for Regioselective C–H Bond Activation and Functionalization

Molecules, 2021
Rollover cyclometalation constitutes a particular case of cyclometallation reaction. This reaction occurs when a chelated heterocyclic ligand loses its bidentate coordination mode and undergoes an internal rotation, after which a remote C–H bond is ...
