The title complex, [RuCl(2)(C(25)H(26)N(2))]·CH(2)Cl(2), is best thought of as containing an octa-hedrally coordinated Ru center with the arene occupying three sites. Two Ru-Cl bonds and one Ru-carbene bond complete the distorted octa-hedron. The carbene portion of the ligand is a benzimidazole ring. This ring is connected to the C(6)H(2)(CH(3))(3) arene group by a CH(2) bridge. This leads to a...

Interactions between three hexacationic arene ruthenium metallaprisms, [(p-cymene)6Ru6(tpt)2(dhnq)3](6+), [(p-cymene)6Ru6(tpt)2(dhbq)3](6+) and [(p-cymene)6Ru6(tpt)2(oxa)3](6+), and a series of human proteins including human serum albumin, transferrin, cytochrome c, myoglobin and ubiquitin have been studied using NMR spectroscopy, mass spectrometry and circular dichroism spectroscopy. All data ...

A novel positively charged pillar[6]arene derivative bearing twelve pyridinium moieties has been synthesized. Its efficient complexation behavior towards two anionic naphthalenesulfonate substrates in aqueous media is described.

The synthesis and characterisation of a small series tethered ruthenium(II) ?6-arene complexes is described, where single benzylic substituent examined as route to enforcing chirality at the metal centre upon ligation bidentate ligand. application these catalysts in asymmetric transfer hydrogenation ketones with moderate enantioselectivities confirming validity approach.

Photo-responsive self-assembly in water based on the molecular recognition motif between a water-soluble pillar[6]arene host and an azobenzene-containing amphiphilic guest in water was investigated.

Arene ruthenium complexes [(h-arene)Ru(sacc)2(OH2)] (arene 1⁄4 para-cymeme, benzene) containing an aqua and two saccharinato ligands have been synthesized from [(h-arene)RuCl2]2 and sodium saccharinate in a water-ethanol mixture (1:1). The aqua complex [(h-MeC6H4Pr)Ru(sacc)2(OH2)] reacts with acetonitrile to give the acetonitrile complex [(h-MeC6H4Pr)Ru(sacc)2(NCMe)]. The corresponding benzene ...

We reveal the ability of p-sulfonatocalix[4/6]arene to effectively inhibit the fibril formation in human insulin and demonstrate its potential to disintegrate the mature fibrils, a promising supramolecular strategy to combat amyloidosis.

A cyclohexadiene ligand prepared by microbial arene 1,2-dihydroxylation undergoes spontaneous rearrangement upon complexation to tricarbonyliron(0). Subsequent iron removal affords a novel route to formal arene 2,3-dihydroxylation products enantiomeric to those obtainable by direct microbial arene oxidation.

an azobenzene bridge was introduced into the lower (or smaller) rim of p-tert-butylcalix[8]arene to form 1,5-singly bridged calix[8]arene derivatives, respectively. bridged calix[8]arene of conformationally rigid wereisolated. the stability of the two structures of bridged calix[8]arenes have been compared.the study of organicstructure to form nanoporous structures is a well known in chemistry ...
