Synthesis, spectral and structural studies of water soluble arene ruthenium (II) complexes containing 2,2?-dipyridyl-N-alkylimine ligand

A series of water soluble complexes of general formula [(eta6- arene)Ru{(C5H4N)2CNRi}Cl]PF6 have been prepared by the reaction of [{(eta6-arene)RuCl 2}2] with appropriate 2,2?-dipyridyl-N-alkylimine ligands (dpNRi) in the presence of NH4PF6 (where; R = Me or Et; arene = p-cymene, C6Me6, C6H 6). The 2,2?-dipyridyl-N-alkylimine ligands are prepared by reaction of 2,2?-dipyridyl ketone with the corresponding alkylamine. The complexes are readily obtained as air stable yellow to dark brown solids by simple stirring at room temperature. The complexes are isolated as their hexafluorophosphate salts and characterized on the basis of spectroscopic data. The molecular structure of representative complex [(eta6-C 6Me6)Ru{(C5H4N)2CN-Me}Cl] PF6 has been determined by single crystal X-ray diffraction studies.

Arene-ruthenium(II) and bis(allyl)-ruthenium(IV) complexes containing 2-(diphenylphosphanyl)pyridine ligands: Potential catalysts for nitrile hydration reactions?

Neutral arene-ruthenium(II) complexes [RuCl2(eta6- arene){kappa1-(P)-PPh2py}] and [RuCl2(eta 6-arene){kappa1-(P)-PPh2(py-4-NMe 2)}] (arene = benzene, p-cymene, mesitylene, hexamethylbenzene) have been synthesized and studied as potential catalysts for the selective hydration of nitriles to amides using benzonitrile as a model substrate. The effectiveness of these complexes was low due to the high tendency of the 2- (diphenylphosphanyl)pyridine ligands to form stable kappa2-(P,N)- chelate rings, as demonstrated by NMR spectroscopy and catalytic experiments performed with the isolated cationic derivatives [RuCl(eta6-arene) {kappa2-(P,N)-P N}][SbF6] [P N = PPh2py, PPh2(py-4-NMe2)]. Despite its reluctance to adopt a chelating kappa2-(P,N) coordination mode, cooperative effects of the bulky 2-(diphenylphosphanyl)pyridine ligand PPh2(py-6-tert-amyl) were not observed in complexes [RuCl2(eta6-arene) {kappa1-(P)-PPh2(py-6-tert-amyl)}] (arene = benzene, p-cymene). The novel bis(allyl)-ruthenium(IV) derivatives [RuCl(eta 3:eta3-C10H16) {kappa2-(P,N)-P N}][SbF6] [P N = PPh2py, PPh2(py-4-NMe2)] and [RuCl2(eta3: eta3-C10H16){kappa1-(P)-PPh 2(py-6-tert-amyl)}] (C10H16 = 2,7-dimethylocta-2,6-diene-1,8-diyl) were also synthesized and fully characterized, and again led to modest conversions in the benzonitrile hydration reaction. Improvements in the catalytic activities of complexes [RuCl 2(eta6-p-cymene){kappa1-(P)-PPh 2py}], [RuCl(eta6-p-cymene){kappa2-(P,N)- PPh2py}][SbF6] and [RuCl(eta3: eta3-C10H16){kappa2-(P,N)- PPh2py}][SbF6] were observed in the presence of excess PPh2py due to the in situ formation of the catalytically more active dication [Ru{kappa2-(P,N)-PPh2py}3] 2+.

New organoruthenium compounds with pyrido[2?,3?:5,6]pyrazino[2,3-f][1, 10]phenanthroline: synthesis, characterization, cytotoxicity, and investigation of mechanism of action

Abstract: Three new ruthenium(II)-arene complexes with pyrido[2?,3?:5,6]pyrazino[2,3-f][1, 10]phenanthroline (ppf) of general formula: C1 ([(?6-benzene)Ru(ppf)Cl]PF6, C2 ([(?6-toluene)Ru(ppf)Cl]PF6) and C3 ([(?6-p-cymene)Ru(ppf)Cl]PF6) have been synthesized. The structures of complexes were determined by elemental analysis, IR, ESI?MS, as well as with 1H and 13C NMR spectroscopy. Cytotoxic activity has been evaluated in three different human neoplastic cell lines (A549, A375, LS 174T) and in one human non-tumor cell line (MRC-5), by the MTT assay. Complexes C1?C3 showed IC50 values in the micromolar range below 100?muM. Complex C3, carrying ?6-p-cymene as the arene ligand, exhibited cytoselective activity toward human malignant melanoma A375 cells (IC50 = 15.8 ¡À 2.7?muM), and has been selected for further analyses of its biological effects. Drug-accumulation study performed in the A375 cells disclosed that C3 possess lower ability of entering the cells compared to cisplatin and distributes approximately equally in the cytosol and membrane/organelle fraction of cells. Investigations in the 3D model of A375 cells, disclosed different effects of the complex C3 and cisplatin on growth of multicellular tumor spheroids (MCTSs). While the size of cisplatin-treated MCTSs decreased with time, MCTSs treated with C3 continued to growth. Differences in structural organization and biological activity of this type of ruthenium(II)-arene complexes versus cisplatin in A375 malignant melanoma cells pointed out their different modes of action, and necessity for further biological studies and optimizations for potential applications.

Synthesis and Structures of Arene Ruthenium (II)?NHC Complexes: Efficient Catalytic alpha-alkylation of ketones via Hydrogen Auto Transfer Reaction

A panel of six new arene Ru (II)-NHC complexes 2a-f, (NHC?=?1,3-diethyl-(5,6-dimethyl)benzimidazolin-2-ylidene 1a, 1,3-dicyclohexylmethyl-(5,6-dimethyl)benzimidazolin-2-ylidene 1b and 1,3-dibenzyl-(5,6-dimethyl)benzimidazolin-2-ylidene 1c) were synthesized from the transmetallation reaction of Ag-NHC with [(eta6-arene)RuCl2]2 and characterized. The ruthenium (II)-NHC complexes 2a-f were developed as effective catalysts for alpha-alkylation of ketones and synthesis of bioactive quinoline using primary/amino alcohols as coupling partners respectively. The reactions were performed with 0.5?mol% catalyst load in 8?h under aerobic condition and the maximum yield was up to 96%. Besides, the different alkyl wingtips on NHC and arene moieties were studied to differentiate the catalytic robustness of the complexes in the transformations.

Novel microwave synthesis of half-sandwich [(eta6-C 6H6)Ru] complexes and an evaluation of the biological activity and biochemical reactivity

We have used a novel microwave-assisted method to synthesize a pair of half-sandwich ruthenium-arene-thiosemicarbazone complexes of the type [(eta6-C6H6Ru(TSC)Cl]PF6. The thiosemicarbazone (TSC) ligands are 2-(anthracen-9-ylmethylene) hydrazinecarbothioamide and 2-(anthracen-9-ylmethylene)-N- ethylhydrazinecarbothioamide derived from 9-anthraldehyde. The complexes are moderately strong binders of DNA, with binding constants of 104 m-1. They are also strong binders of human serum albumin, having binding constants of the order of 105 m-1. The complexes show some in vitro anticancer activity against human colon cancer cells, Caco-2 and HCT-116, with positive therapeutic indices. They did not show any activity as antibacterial agents against the organisms that were studied. Copyright

Optically active P5-deltacyclenes: Selective oxidation, ligand properties, and a diastereoselective rearrangement reaction

Cage-chiral tetra-tert-butyl-P5-deltacyclene 5 is accessible as a pair of highly enriched enantiomers 5? and 5?. The only secondary phosphorus atom P1 of the cage can be selectively oxidized by reaction with t-BuOOH. The P1-oxo species 9a? and 9a?, allow the direct determination of their ee values. Oxidation occurs with the complete retention of the optical activity of the compounds. The chiroptical properties of 9a? and 9a? are strongly dominated by their cage chirality, the oxygen atom does not contribute significantly. Elemental sulfur and selenium oxidize P5 with high preference to yield P5-thio- and P5-seleno-P5-deltacyclenes 10 and 11 of the intact cages again. Longer reaction time and more than stoichiometric amounts of selenium, leads to tri-seleno-P5-tetracycloundecane 12, a partially opened oxidized rearrangement product. The ligand properties of racemic 9a were determined. Diphosphetane phosphorus atom P2 of 9a is the active donor center to bind a Cr(CO)5 fragment, but a tautomerization of 9a takes place if [(benzene)RuCl2]2 is added. A hydrogen atom migrates from P1 to the oxygen atom to form a phosphinous acid ligand. The lone pair of P1 is regenerated and acts as the active ligand function of the cage in this case. As for 5, the base n-BuLi induces an efficient cage rearrangement reaction of 9a, where P1 and the neighboring carbon atom C4 containing its t-Bu substituent change places. C4 moves to its new position without breaking the bond with P5, this way forming the novel P1-oxo-P5-norsnoutene cage in a highly diastereoselective process.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 37366-09-9, you can also check out more blogs about37366-09-9
