Catalytic hydride delivery from in situ generated metal hydride complexes to substrates represents an important process in a variety of catalysis. Investigations revealed a “multidimensional synergistic control” among the stereoelectronic factors—yaw angle, bite angle, as well as the electronic properties of both the ligand and the metal center within the cyclometalated iridium catalysts—that govern the hydride donor ability (hydricity) of the complexes during catalysis. A frontier molecular orbital analysis provided the rationale of such a correlation. For more details, see the Full Paper by J. Choudhury et al. on page 13051 ff.
