Kinds of Carbene Complexes Selected AbstractsA Facile One-Step Synthesis of a Lipophilic Gold(I) Carbene Complex ,X-ray Crystal Structures of LAuCl and LAuC,CH (L = 1,3-di- tert- Butylimidazol-2-ylidene)EUROPEAN JOURNAL OF INORGANIC CHEMISTRY, Issue 15 2005Sanjay Singh Abstract The reaction of Au(CO)Cl with 1,3-di- tert -butylimidazol-2-ylidene and 1,3-dimesitylimidazol-2-ylidene in toluene at room temperature results in CO evolution and readily affords in high yield the adducts 1a and 1b, respectively. The reaction of 1a and 1b with ethynylmagnesium chloride in THF yields 2a and 2b, respectively. The crystal structures of 1a, 1b, and 2a were determined. (© Wiley-VCH Verlag GmbH & Co.

[source] Synthesis and in vitro Efficacy Studies of Silver Carbene Complexes on Biosafety Level 3 BacteriaEUROPEAN JOURNAL OF INORGANIC CHEMISTRY, Issue 13 2009Matthew J. Panzner Abstract A series of N-heterocyclic carbene silver complexes have been synthesized and tested against the select group of biosafety level 3 bacteria Burkholderia pseudomallei, Burkholderia mallei, Bacillus anthracis, methicillin-resistant Staphylococcus aureus and Yersinia pestis. Minimal inhibitory concentrations, minimal bactericidal and killing assays demonstrated the exceptional efficacy of the complexes against these potentially weaponizable pathogens.

Treatment of 3 under reflux in toluene and removing all the volatiles in vacuo afforded the dimeric compound [{HC(CMeNAr)2}Mn]2(,-I)2 (4). Displacement of the coordinated THF in 3 by a strong Lewis base C[N(iPr)CMe]2 or by adding C[N(iPr)CMe]2 to the toluene solution of 4 readily gave the N-heterocyclic carbene adduct [{HC(CMeNAr)2}]MnI{C[N(iPr)CMe]2} (5). Reduction of 5 with sodium/potassium alloy at room temperature unexpectedly resulted in the formation of the monomeric compound [{HC(CMeNAr)2}]MnNHAr{C[N(iPr)CMe]2} (6). Alternatively 6 was obtained by the salt elimination reaction of 5 with LiNHAr. Compounds 5 and 6 are the first examples of divalent manganese N-heterocyclic carbene adducts and the first manganese non-carbonyl carbene complexes. The single crystal X-ray structural analyses reveal that compounds 3 and 6 are monomeric and compound 4 is dimeric in the solid state. The manganese centers in these compounds exhibit a distorted tetrahedral geometry. (© Wiley-VCH Verlag GmbH & Co.
