Three different {eta5-(+)-neomenthylcyclopentadienyl}ruthenium complexes have been synthesized from (-)-menthol: [(eta6-benzene){eta5-(+)- neomenthylcyclopentadienyl}ruthenium(II)] hexafluorophosphate (1), [tris(acetonitrile) {eta5-(+)-neomenthylcyclopentadienyl}ruthenium(II)] hexafluorophosphate (2) and [eta6-cyclooctatetraene) {eta5-(+)-neomenthylcyclopentadienyl}ruthenium(II)] hexafluorophosphate (3). X-ray structural determination (space group P212121) and NMR spectroscopic studies of 3 show it exists as a single stereoisomer in both the solid and solution phase, with [alpha]20D = +92.5. The chiral modification of the Cp ligand induces anisochrony for all of the magnetically active nuclei of the unsubstituted COT ligand.

The reactions of PhSe-, PhS- and Se2- with N-{2-(chloroethyl)}pyrrolidine result in N-{2-(phenylseleno)ethyl}pyrrolidine (L1), N-{2-(phenylthio)ethyl}pyrrolidine (L2), and bis{2-pyrrolidene-N-yl)ethyl selenide (L3), respectively, which have been explored as ligands. The complexes [PdCl2(L1/L2)] (1/7), [PtCl2(L1/L2)] (2/8), [RuCl(eta6-C6H6)(L1/L2)][PF6] (3/9), [RuCl(eta6-p-cymene)(L1/L2)][PF6] (4/10), [RuCl(eta6-p-cymene)(NH3)2][PF6] (5) and [Ru(eta6-p-cymene)(L1)(CH3CN)][PF6]2·CH3CN (6) have been synthesized. The L1-L3 and complexes were found to give characteristic NMR (Proton, Carbon-13 and Se-77). The crystal structures of complexes 1, 3-6, 9 and 10 have been solved. The Pd-Se and Ru-Se bond lengths have been found to be 2.353(2) and 2.480(11)/2.4918(9)/2.4770(5) A?, respectively. The complexes 1 and 7 have been explored for catalytic Heck and Suzuki-Miyaura coupling reactions. The value of TON has been found up to 85 000 with the advantage of catalyst’s stability under ambient conditions. The efficiency of 1 is marginally better than 7. The Ru-complexes 3 and 9 are good for catalytic oxidation of primary and secondary alcohols in CH2Cl2 in the presence of N-methylmorpholine-N-oxide (NMO). The TON value varies between 8.0 × 104 and 9.7 × 104 for this oxidation. The 3 is somewhat more efficient catalyst than 9.

The synthesis of [{RuCl2(eta6-o-MeC6H4CO 2Me)}2], (o-MeC6H4CO2Me = methyl o-toluate), from RuCl3·3H2O and methyl 1,4-dihydro-o-toluate is reported. This is the first example of an arene-ruthenium complex having planar chirality with respect to the face of the co-ordinated arene. Its reactions with tertiary phosphines and primary amines have been examined. Using optically active amines, the complexes [RuCl2(eta6-o-MeC6H4CO 2Me) L?] [L? = (-)(S)-1-phenylethylamine or (+)-dehydroabietylamine], and [RuCl(eta6-o-MeC6H4CO 2Me)(N-N)]PF6 [N-N = (-)(R,R)-1,2-diphenyl-1,2-diaminoethane], have been obtained as diastereomeric mixtures. The diastereomers of [RuCl2(eta6-o-MeC6H4CO 2Me){(-)(S)-MeCH(Ph)NH2}] have been partially separated by fractional crystallisation, the less soluble one being obtained with > 90% enrichment. Their circular dichroism spectra have been compared with those of complexes containing achiral arene-ruthenium moieties.

The interest in therapeutical applications of carbon monoxide to physiological targets has led us to explore CO releasing molecules (CORM’s), particularly those that decomposes upon a specific stimuli, i.e. light irradiation. Here, we prepared a photoactivated, air stable and water soluble ruthenium(II) complex, cis-[Ru(bpy)2(SO3)(CO)], which releases carbon monoxide upon light irradiation. Indeed, many CORMs face very limited water solubility calling for improving this drawback. Photolysis of this complex using UV light in aqueous solution leads to high quantum yield of a single CO release. The release of CO was confirmed by myoglobin assay, and a careful monitoring of this photo-reaction was performed using HPLC. Our results showed it might serves as a carbon monoxide releasing moiety, which can be induced photochemically. Despite the lack of pharmacological and toxicological studies, these results are quite encouraging and might eventually lead this compound to become a relevant pharmacological agent.

Reference of 15746-57-3. Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II)

The compounds [(acac)2RuIII(mu-H2L 2-)RuIII(acac)2] (rac, 1, and meso, 1?) and [(bpy)2RuII(mu-H2L?-) RuII(bpy)2](ClO4)3 (meso, [2](ClO4)3) have been structurally, magnetically, spectroelectrochemically, and computationally characterized (acac- = acetylacetonate, bpy = 2,2?-bipyridine, and H4L = 1,4-diamino-9,10-anthraquinone). The N,O;N?,O?-coordinated mu-H2Ln- forms two beta-ketiminato-type chelate rings, and 1 or 1? are connected via NH···O hydrogen bridges in the crystals. 1 exhibits a complex magnetic behavior, while [2](ClO4)3 is a radical species with mixed ligand/metal-based spin. The combination of redox noninnocent bridge (H 2L0 ? ? ? ?H2L 4-) and {(acac)2RuII} ? ?{(acac) 2RuIV} or {(bpy)2RuII} ? {(bpy)2RuIII} in 1/1? or 2 generates alternatives regarding the oxidation state formulations for the accessible redox states (1n and 2n), which have been assessed by UV-vis-NIR, EPR, and DFT/TD-DFT calculations. The experimental and theoretical studies suggest variable mixing of the frontier orbitals of the metals and the bridge, leading to the following most appropriate oxidation state combinations: [(acac) 2RuIII(mu-H2L?-)Ru III(acac)2]+ (1+) ? [(acac)2RuIII(mu-H2L2-)Ru III(acac)2] (1) ? [(acac)2Ru III(mu-H2L?3-)RuIII(acac) 2]-/[(acac)2RuIII(mu-H 2L2-)RuII(acac)2]- (1-) ? [(acac)2RuIII(mu-H 2L4-)RuIII(acac)2] 2-/[(acac)2RuII(mu-H2L 2-)RuII(acac)2]2- (12-) and [(bpy)2RuIII(mu-H2L?-) RuII(bpy)2]4+ (24+) ? [(bpy)2RuII(mu-H2L?-)Ru II(bpy)2]3+/[(bpy)2Ru II(mu-H2L2-)RuIII(bpy) 2]3+ (23+) ? [(bpy)2Ru II(mu-H2L2-)RuII(bpy) 2]2+ (22+). The favoring of RuIII by sigma-donating acac- and of RuII by the pi-accepting bpy coligands shifts the conceivable valence alternatives accordingly. Similarly, the introduction of the NH donor function in H2L n as compared to O causes a cathodic shift of redox potentials with corresponding consequences for the valence structure.

A chloride anion templation methodology is utilized in the construction of novel transition-metal rhenium(I) and ruthenium(II) bipyridyl appended [2]rotaxanes. 1H NMR spectroscopic titrations reveal the ability of the rotaxanes to selectively bind chloride over the more basic oxoanions, with the ruthenium(II) bipyridyl appended rotaxane strongly binding chloride in 30 % water. Photophysical investigations demonstrate the ability of the rotaxanes to sense anions in aqueous media, with chloride being selectively complexed, in general agreement with NMR spectroscopy determined anion binding data.
