Cyclometallation of 8‐methylquinoline and 2‐(dimethylamino)‐pyridine in an iridium‐based pincer complex is described. The C−H activation of 2‐(dimethylamino)pyridine is not chelation assisted, which has not been described before for Csp 3 −H bonds in cyclometallation reactions. The mechanism of the cyclometallation of 2‐(dimethylamino)pyridine was studied by DFT calculations and kinetic measurements.
