Several nitrosyl complexes of Fe and Co have been prepared using the sterically hindered Ar-nacnac ligand (Ar-nacnac = anion of [(2,6- diisopropylphenyl)NC(Me)]2CH). The dinitrosyliron complexes [Fe(NO)2(Ar-nacnac)] (1) and (Bu4N)[Fe(NO) 2(Ar-nacnac)] (2) ...

A [FeIIFeII] dithiolate complex containing acyl and carbonyl ligands was synthesized. The diiron complex reacted with phosphine, cyanide, isocyanide, and CO to give monomeric FeII complexes reproducing the first coordination sphere of the active site of [F ...

Numerous inorganic and organic micropollutants can undergo reactions with chlorine. However, for certain compounds, the expected chlorine reactivity is low and only small modifications in the parent compound's structure are expected under typical water tre ...

The cationic complexes [(η6-arene)Ru(SC5H4NH)3]2+, arene being C6H6 (1), MeC6H5 (2), p-iPrC6H4Me (3) or C6Me6 (4), have been synthesized from the reaction of 4-pyridinethiol with the corresponding precursor (η6-arene)2Ru2(μ2-Cl)2Cl2 and isolated as the chl ...

The Hydration of Chloroacetonitriles Catalyzed by Mono- and Dinuclear Ru-II- and Os-II-Arene Complexes

Christian Hartinger, Alexey Nazarov

The hydration of nitrites to the corresponding amides is all important reaction for both laboratory and industry purposes. The classical synthesis method requires harsh conditions, gives low yields, and is nonselective due to further hydrolysis of the amid ...

Analysis of the Synergistic Effect of Carbonylplatinum Complexes on the Iridium-Catalysed Carbonylation of Methanol to Acetic Acid

Gabor Laurenczy

High-pressure NMR mechanistic investigations into the promoting role of dicarbonyldiiodoplatinum complex in the iridium-catalysed carbonylation of methanol to acetic acid are consistent with iodide abstraction from the [IrI3(CH3)(CO)2]– resting state speci ...

Direct reaction between [Cr(CO)6] and arenes with ionic substituents affords the corresponding arene-chromium tricarbonyl complexes, [Cr(CO)3(arene)], in only modest yield. In contrast, these complexes can be prepared in pure form in ...

The acid-catalyzed cyclization-condensation between anilines and Et 4,4,4-trifluoroacetoacetate affords 1,4-dihydro-2-trifluoromethyl-4H-4-quinolinones, which can easily be converted into 4-bromo-2-(trifluoromethyl)quinolines. These undergo halogen/metal e ...
