Chemistry - A European Journal [LCSOM]

Abstract The   performance   of   six   newly   synthesized benzo[h]quinoline-derived  acetonitrilo  pentamethylcyclopentadienyl iridium(III) tetrakis(3,5-bis-trifluoromethylphenyl)borate salts bearing different substituents -X (-OMe, -H, -Cl, -Br, -NO2 and –(NO2)2) on the heterochelating ligand were evaluated in the dehydro-O-silylation of   benzyl   alcohol   and   the   monohydrosilylation  ...[En savoir plus]

Chem. Eur. J. [LCC]

Abstract Carbonylmetallates [m]−, such as [MoCp(CO)3]−, [Mn(CO)5]−, [Co(CO)4]−, have long been successfully used in the preparation of hundreds of metal-metal bonded carbonyl complexes and clusters, in particular of the heterometallic type. We focus here on situations where [m]− can be viewed as a terminal, doubly or even triply bridging metalloligand, developing metal-metal interactions with...[En savoir plus]

Eur. J. Inorg. Chem. [CLAC]

Abstract: This article covers 50 years of coordination chemistry of transition metal complexes and metal-sulfur aggregates involving thiolate-incorporating ligands by reviewing selected examples. The studies in the coordination chemistry of sulfur-rich ligands have been undoubtedly triggered and fed by the concomitant development of bioinorganic chemistry, particularly of iron-sulfur enzymes....[En savoir plus]

Inorganic Chemistry [BCB/POMAN]

Abstract α-Pyridyl thiosemicarbazones (TSC) such as Triapine (3AP) and Dp44mT are a promising class of anticancer agents. Contrary to Triapine, Dp44mT showed a pronounced synergism with CuII, which may be due to the generation of reactive oxygen species (ROS) by Dp44mT-bound CuII ions. However, in the intracellular environment, CuII complexes have to cope with glutathione (GSH), a relevant CuII...[En savoir plus]

Angewandte Chemie [BCB]

Abstract The redox activity of Cu ions bound to the amyloid-β (Aβ) peptide is implicated as a source of oxidative stress in the context of Alzheimer's disease. In order to explain the efficient redox cycling between Cu(II)-Aβ (distorted square pyramidal) and Cu(I)-Aβ (digonal) resting states, the existence of a low-populated "in-between" state, prone to bind Cu in both oxidation states, has been...[En savoir plus]

Org. Lett. [SOPHY]

Abstract We report herein a domino reaction to construct 2-amido-5-fluoropyrroles from CF3-substituted N-allenamides. The in situ generated gem-difluorinated ene-ynamides derived from CF3-substituted N-allenamides, when subjected to silver catalysis with a primary amine, undergo simultaneous hydroamination of the ynamide moiety followed by a 5-endo-trig addition/β-fluoride elimination sequence,...[En savoir plus]
