Reactions between N-heterocyclic carbenes (NHCs) and the trityl cation, [Ph3C]+, give covalent adducts of type [NHC–CPh3]+ and/or [NHC–C6H5–CPh2]+. EPR spectroscopy, UV-Vis analyses, and trapping experiments imply that adduct formation involves carbene rad ...

Dinudear metal complexes have emerged as a promising class of anticancer compounds with the ability to cross-link biomolecular targets. Here, we describe two novel series of phosphine-linked dinudear ruthenium(II) p-cyrnene and gold(I) complexes, in which ...

Raw data accompanying the paper. Metal-arene complexes have recently attracted an increasing interest in f-element chemistry, but the functionalization of arenes mediated by uranium-arene interactions is limited to a single example. Here, we report a new ...

The 2,3-anti-3,4-syn-stereotriad (1Z,2S,3R,4S)-1-ethylidene-2,4-dimethyl-3-[(1S)-1-phenylethoxy]-5-oxopent-1-yl isobutyrate {(-)-8, obtained in a one-pot operation from the trimethylsilyl (Z)-enol ether derived from pentan-3-one and (1E,3Z)-1[(1S)-phenylet ...

Four tetracatenar (L1–L4) and one hexacatenar (L5) ligands, derived from the diaza-18-crown-6 framework, are synthesized and characterized. In these ligands, the amine functions are fitted with benzoyloxybenzyl linker groups, attached either with a carbony ...

Ditopic N-donor ligands with terminal 4-pyridyl groups are omnipresent in coordination-based self-assembly. The utilization of ligands with 3-pyridyl donor groups is significantly less common, because the intrinsic conformational flexibility of these ligan ...

Reaction of 1,1'-bis(diphenylphosphino)binaphthol (BINAPO, 1) with [RuCl2(η6-arene)]2 in methanol leads to dinuclear BINAPO-bridged Ru compounds [{RuCl2(η6-p-cymene)}2-(μ-BINAPO)], 2a, in ne ...

The reaction of nitrous oxide (N2O) with N-heterocyclic olefins (NHOs) results in cleavage of the N–O bond and formation of azo-bridged NHO dimers. The latter represent very electron-rich compounds with a low ionization energy. Cyclic voltammetry studies s ...

The reaction of (Et3P)PdCl2 with 2,3-dihydroxypyridine, 5-chloro-2,3,-dihydroxypyridine, or 2-hydroxynicotinic acid in the presence of base gives neutral, metallomacrocyclic compounds in which the heterocycles act as dianionic, bridging ligands. The m ...

Following the identification of [Ru(eta(6)-p-cymene)Cl-2(1H,1H,2H,2H-perfluorodecyl-3-(pyridin-3-yl)propanoate)], a ruthenium(II)arene complex with a perfluoroalkyl-modified ligand that displays remarkable in vitro cancer cell selectivity, a series of stru ...

One tetrahedral and two trigonal prismatic cages with π-basic Au3(pyrazolate)3 faces were obtained by connection of pre-formed gold complexes via dynamic covalent imine chemistry. The parallel arrangement of the Au3(pyrazolate)3 complexes in the prismatic ...

A series of ether-derivatized imidazolium halides have been prepd. and characterized. Contrary to literature reports, they are all cryst. solids and have m.ps. well above room temp. (50-100 °C). Single crystals of the imidazolium salts, obtained in situ by ...

5-Hydroxymethylfurfural (HMF) is a key platform chemical that may be obtained from various cellulosic (biomass) derivatives. Previously, it has been shown that ionic liquids (ILs) facilitate the catalytic conversion of glucose into HMF. Herein, we demonstr ...

Two hybrid compounds comprising an antimetastatic rutheniumarene fragment tethered to an indazole-3-carboxylic acid derivative that inhibits aerobic glycolysis in cancer cells have been prepared and evaluated in a variety of cancer cell lines, including hi ...

We report the first comprehensive comparative synthetic, structural, electrochemical, and spectroscopic study of an extended series of fluorocarbon-modified iridium(III) complexes. We prepared seven new cationic Ir(III) complexes with tert-butyl isocyanide ...

Bent (hetero)allenes such as carbodicarbenes and carbodiphosphoranes can act as neutral C-donor ligands, and diverse applications in coordination chemistry have been reported. N-Heterocyclic diazoolefins are heterocumulenes, which can function in a similar ...

A synthetic procedure for the synthesis of two molecular borophosphate cages is described. Heating of ethyl phosphate with phenylboronic or 4-formylboronic acid in toluene gives [6+6] condensation products of the general formula EtOPO3BAr. Crystallogr ...

Boronic acid-capped clathrochelates were used to build rigid, linear bipyridyl ligands with adjustable lengths between 1.5 and 5.4 nm. The syntheses can be accomplished in one or two steps from simple starting materials. The potential of these ligands as b ...

The reaction of chloromethyl thiocyanate with 1-methylimidazole affords the imidazolium salt, 1-thiocyanomethyl-3-methylimidazolium chloride, [C1SCNmim]Cl (1a). Exchange of the chloride anion in 1a by [PF6] ...
