Web4 aug. 2024 · Metal-ligand cooperativity represents a valuable strategy for utilizing abundant elements to develop economically viable catalytic transformations. We believe there are many unspoken similarities between d-block metal-ligand cooperativity, frustrated Lewis pairs, and other recent developments in the p-block. Metal-ligand cooperativity (MLC) is a mode of reactivity in which a metal and ligand of a complex are both involved in the bond breaking or bond formation of a substrate during the course of a reaction. This ligand is an actor ligand rather than a spectator, and the reaction is generally only deemed … Meer weergeven There are a variety of modes in which this cooperativity has been demonstrated. Four primary modes are generally accepted under MLC: the ligand can (1) act with Lewis acidity, (2) act with Lewis basicity, (3) … Meer weergeven MLC is most frequently used in hydrogenations, with many applications in asymmetric catalysis and in process scale production of chemicals.
