Organic Geochemistry [Biogéochimie Moléculaire]

Abstract Lipid biomarkers, such as the various bacteriohopanetetrol (BHT) isomers studied here, are useful tools in tracing bacterially mediated nitrogen and carbon cycle processes affecting greenhouse gas emissions, including the anaerobic oxidation of ammonia. Three BHT isomers occur commonly in the environment. By gas chromatography, BHT-34S elutes first; it is produced by numerous bacteria....[En savoir plus]

Chemical Communications [CLAC]

Abstract A bipyridine-strapped porphyrin was prepared using a remote template effect of alkali or transition metal cations in the bipyridine subunit to enhance the yield 10-fold. The flexibility of the bipyridine-strap also allowed the synthesis of a doubly strapped porphyrin. Reference Remote template effect in the synthesis of bipyridine-strapped porphyrins M. Berthe, Y. Kagawa, A....[En savoir plus]

Eur. J. Inorg. Chem. [CLAC]

Abstract Six- and seven-membered cyclic hydroxamic acids are found as terminal binding units in different families of siderophores, including exochelins and mycobactins. The simplest models of these preorganized chelating ligands were known, but their coordination chemistry with Fe3+, the target metal ion of siderophores, had never been reported. Four complexes were synthesized and studied: two...[En savoir plus]

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]
