Web9 dec. 2024 · (a) The concept of metal–ligand cooperation according to the criteria defined by Khusnutdinova and Milstein. (b) Hydrogen activation by Noyori's catalyst. (c) Reversible hydrogen activation by Milstein's pyridine-based pincer complex through an aromatization/de-aromatization sequence. WebWe found that ligands that are more electron-deficient lead to more favorable reactions, in sharp contrast to classical metal-centered oxidative additions. This trend is in good agreement with the proposed mechanism, in which C–H bond cleavage is accompanied by two-electron transfer from the metal center to the cyclopentadienone ligand.

Web7 sep. 2015 · Metal–ligand cooperation (MLC) has become an important concept in catalysis by transition metal complexes both in synthetic and biological systems. MLC implies that … 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 to contain MLC if the actor ligand is doing more than leaving to provide an open coordination site. MLC is also referred to as "metal-ligand bifunctional catalysis." Note that ML…
