Recent Developments in the Medicinal Applications of Silver-NHC Complexes and Imidazolium Salts.
Because of their great structural diversity and multitude of chemical properties, N-heterocyclic carbenes (NHCs) have been utilized in a variety of capacities. Most recently, NHCs have been utilized as carrier molecules for many transition metals in medicinal chemistry. Specifically, Ag(I)-NHCs have been investigated as potent antibacterial agents and chemotherapeutics and have shown great effi...
متن کاملStructure and reactivity of "unusual" N-heterocyclic carbene (NHC) palladium complexes synthesized from imidazolium salts.
The reaction between palladium acetate and IMES.HCl leads to the formation of a novel palladium complex. The X-ray crystal structure analysis reveals that the palladium is C(2) bound to one NHC ligand (the normal binding mode), whereas the second ligand is attached through the C(5) carbon of the second imidazolium. The metalation site on the imidazolium salt is strongly influenced by the presen...

متن کاملSynthesis and Characterization of Di- and Tetracarbene Iron(II) Complexes with Chelating N-Heterocyclic Carbene Ligands and Their Application in Aryl Grignard−Alkyl Halide Cross-Coupling
A series of new and known bis(imidazolium) chloride and bromide salts bridged by either a methylene group (1−8, 10a,b) or an ethylene group (9a,b) and bearing different N substituents (Me, Et, Bn, tBu, Mes) have been reacted with [Fe{N(SiMe3)2}2]2 to yield the four-coordinate iron(II) complexes [LFeX2] (11−20; X = Cl, Br; L = chelating bis(imidazolylidene) ligand). Molecular structures of six o...
متن کاملNormal and Abnormal Bonding of N-Heterocyclic Carbenes: Impact on Stability, Reactivity, and Catalysis
N-heterocyclic carbenes (NHCs), typically derived from imidazolium salts, have provided highly powerful ligands for catalysis. Recently, abnormal C4 bonding rather than normal C2 bonding has been discovered as a new carbene bonding mode. We were interested in comparing the consequences of these two bonding modes on the metal center. Therefore we synthesized related palladium complexes 1 and 2 c...
