A series of arene–ruthenium complexes of the general formula [RuCl2{g-C6H5(CH2)2R}L] with R1⁄4OH, CH2OH, OC(O)Fc, CH2OC(O)Fc (Fc1⁄4 ferrocenyl) and L1⁄4PPh3, (diphenylphosphino)ferrocene, or bridging 1,10-bis(diphenylphosphino)ferrocene, have been synthesized. Two synthetic pathways have been used for these ferrocene-modified arene–ruthenium complexes: (a) esterification of ferrocene carboxylic...

Two ruthenium(II) complexes, Λ-[Ru(phen)(2)(p-HPIP)](2+) and Δ-[Ru(phen)(2)(p-HPIP)](2+), were synthesized and characterized via proton nuclear magnetic resonance spectroscopy, electrospray ionization-mass spectrometry, and circular dichroism spectroscopy. This study aims to clarify the anticancer effect of metal complexes as novel and potent telomerase inhibitors and cellular nucleus target dr...

A series of bimetallic N-heterocyclic carbene (NHC) ruthenium(II) complexes were synthesized, which comprise two [RuCl(2)(cymene)(NHC)] units that are interlinked via the NHC nitrogens by alkyl chains of different length. Electrochemical characterization revealed two mutually dependent oxidation processes for the complex with a methylene linker, indicating moderate intramolecular electronic cou...

Triplet-triplet annihilation upconversion (TTA-UC) is a promising photophysical tool to shift the activation wavelength of photopharmacological compounds to the red or near-infrared wavelength domain, in which light penetrates human tissue optimally. However, TTA-UC is sensitive to dioxygen, which quenches the triplet states needed for upconversion. Here, we demonstrate not only that the sensit...

The catalytic activity of ruthenium(II) bis(diimine) complexes cis-[Ru(6,6′-Cl2bpy)2(OH2)2](Z)2 (1, Z=CF3SO3; 2, Z= (3,5-(CF3)2C6H3)4B, i.e. BArF) and cis-[Ru(4,4′-Cl2bpy)2(OH2)2](Z)2 (3, Z=CF3SO3; 4, Z=BArF) for the hydrogenation and/or the hydrogenolysis of furfural (FFR) and furfuryl alcohol (FFA) was investigated. Themolecular structures of cis-[Ru(4,4′-Cl2bpy)2(CH3CN)2](CF3SO3)2 (3′) and d...

The synthesis by transmetallation and in-depth characterisation IR spectroscopy of five half-sandwich ruthenium osmium dithiocarbamato isonipecotamide glycoconjugate complexes are presented herein. evaluation their in vitro cytotoxicity the zinc precursors’ towards ovarian cancer (A2780 A2780cisR) normal prostate (PNT2) cells is reported. While compounds rather limited, some selectivity observed.

The dimeric η(6)-hexamethylbenzene ruthenium(II) triazole compounds of formulation [{(η(6)-C(6)Me(6))Ru(N(3)C(2)(CO(2)R)(2))}(2)(μC(2)O(4))] have been synthesized by 1,3-diploar cycloadditions of coordinated azido compound [{(η(6)-C(6)Me(6))Ru(L(1))N(3)}] (1) with substituted acetylene, RO(2)CC(2)CO(2)R via unexpected oxidation of the coordinated ligand to oxalate (where; L(1) = 5-hydroxy-2-(hy...
