Pincer Complexes and Transition Metal Bond Activation
This community focuses on the synthesis and structural characterization of transition metal complexes, specifically those utilizing pincer ligands, to study fundamental bond activation and catalytic reactivity.
The work centers on the design of pincer ligands and their coordination to metals such as iridium, rhodium, platinum, palladium, and nickel. Recurring themes include the investigation of oxidative addition, bond cleavage, and the formation of carbonyl clusters. Researchers frequently report on the synthesis of these complexes, their crystal structures, and their reactivity in catalytic cycles. The literature emphasizes the electronic and steric properties of the ligand environment and its influence on the metal center's ability to activate strong bonds, such as C–H and H–H bonds. Specific attention is paid to the stability of intermediates and the mechanisms governing electron transfer and radical processes within these organometallic systems.
The community is most significant in the research tracked for rhodium, representing 15.1% of all rhodium research, and 7.7% of iridium research. It also constitutes 5.2% of palladium research. The element with the highest paper count within this group is platinum, with 5,798 papers.
There are 40,207 papers in this community, primarily published in the Journal of Organometallic Chemistry, Organometallics, and Inorganic Chemistry.
Recent work continues to explore stereospecific cross-coupling, metal–metal bond dissociation dynamics, and the electronic configurations of heterometallic chains. Newer studies also examine solvent-dependent reactivity in rhodium complexes and the catalytic cyclopropanation of vinyl arenes using platinum catalysts.
