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), Formula: C20H16Cl2N4Ru.

We report a sustainable in vitro system for enzyme-based photohydrogen production. The [FeFe]-hydrogenase HydA1 from Chlamydomonas reinhardtii was tested for photohydrogen production as a proton-reducing catalyst in combination with eight different photosensitizers. Using the organic dye 5-carboxyeosin as a photosensitizer and plant-type ferredoxin PetF as an electron mediator, HydA1 achieves the highest light-driven turnover number (TONHydA1) yet reported for an enzyme-based in vitro system (2.9×106 mol(H2) mol(cat)?1) and a maximum turnover frequency (TOFHydA1) of 550 mol(H2) mol(HydA1)?1 s?1. The system is fueled very effectively by ambient daylight and can be further simplified by using 5-carboxyeosin and HydA1 as a two-component photosensitizer/biocatalyst system without an additional redox mediator.

The whole “pybox” and dice: Highly enantioselective amination reactions of both allylic and benzylic C-H bonds are catalyzed by cationic ruthenium(II)-pybox complexes (see structure). A novel mode of stereocontrol, which is induced by the versatile pybox ligand, is proposed to account for the excellent enantioselectivity in these reactions. Boc = tert-butoxycarbonyl, pybox = pyridine bisoxazoline. (Chemical Equation Presented)

A chemically functionalized nanocrystalline TiO2 grafted ruthenium(ii) polyazine complex was found to be an efficient visible light photoredox catalyst for the oxidative cyanation of tertiary amines to the corresponding alpha-aminonitriles in high to excellent yields, using molecular oxygen as an oxidant and sodium cyanide in acetic acid as a cyanide source. The developed photoredox catalyst could be easily recovered by simple filtration and reused for several runs with consistent catalytic activity.

A document type is Article, introducing its new discovery.

Allylic chlorides prepared from commercially available trans-1,4-dichloro-2-butene were converted to trans-disubstituted 5- and 6-membered ring systems with perfect diastereoselectivity and high enantioselectivity under chiral ruthenium catalysis. These products contain stereodefined secondary and tertiary alcohols that originate from the trapping of an alkylruthenium intermediate with adventitious water. Key to the success of this transformation was the development of a new BINOL-based phosphoramidite ligand containing bulky substitution at its 3- and 3?-positions. As a demonstration of product utility, diastereoselective Friedel-Crafts reactions were performed on the chiral benzylic alcohols in high yield and stereoselectivity.

Application of 246047-72-3. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 246047-72-3, Name is (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium. In a document type is Article, introducing its new discovery.

Phosphine-scavenging resins can significantly facilitate the synthesis of highly active Ru metathesis catalysts, including the second-generation Grubbs, Hoveyda, and indenylidene catalysts (GII, HII, InII). These catalysts are customarily prepared by ligand exchange of the corresponding first-generation catalysts with the N-heterocyclic carbene (NHC) H2IMes. The PCy3 coproduct is conventionally removed by pentane extraction, but the partial solubility of the desired Ru products can cause product losses of over 20%. Sequestration of the PCy3 coproduct with CuCl is more efficient, but is undesirable given the potential for non-innocent copper residues. Use of the arylsulfonic acid resin Amberlyst-15 delivers near-quantitative catalyst yields, but the high acidity of the resin leads to problems with reproducibility and decomposition. An alternative approach is described, in which a neutral Merrifield resin (crosslinked polystyrene with pendant p-C6H4CH2I groups; MF-I) is used to sequester PCy3 as the covalently-tethered benzylphosphonium salt. Addition of MF-I following complete ligand exchange effects quantitative uptake of free PCy3 (and any residual free NHC) within 45 min at RT: the clean products are isolated by filtration, in ca. 95% yield. These yields compare well with those obtained via the Amberlyst-15 route, without the challenges due to resin acidity. The efficacy of this methodology is demonstrated in the synthesis of isotopically-labelled derivatives of HII, in which the H2IMes ligand bears a 13C-label at the carbene carbon, or perdeuterated mesityl rings.

The synthesis and anion-recognition properties of two new porphyrin-functionalised [2]rotaxane host molecules are described. The rotaxane compounds are prepared via a chloride-anion-templated clipping strategy. 1H NMR titration experiments demonstrate that the rotaxane host systems exhibit high binding affinities and general selectivities for chloride anions in DMSO-d6 or CDCl3/CD3OD solvent systems. UV-visible and fluorescence spectroscopy experiments reveal that the rotaxane receptors are ineffective as optical anion sensors. However, both receptors are shown to be capable of detecting chloride anions electrochemically via cathodic shifts in the porphyrin P/P+ redox couples. The Royal Society of Chemistry.

New benzene ruthenium(II) aroylhydrazone complexes of general molecular formula [Ru(eta6-C6H6)Cl(L)] (where L = aroylhydrazone ligand) have been synthesized from the reaction of the precursor [Ru(eta6-C6H6)(mu-Cl)Cl]2and aroylhydrazone ligands. The composition of the complexes has been accomplished by elemental analysis and spectral methods (FT-IR, UV-Vis,1H NMR). The molecular structure of complex 4 has been established by single-crystal X-ray structure analysis shows that the aroylhydrazone ligands are coordinated to ruthenium as a bidentate N, O donor and a typical piano stool geometry was observed around ruthenium(II) metal center. All the complexes exhibit two consecutive irreversible oxidations in the potential range +0.74 to +1.17 V (RuII/RuIII;RuIII/RuIV) Vs calomel electrode. Further, in vitro anticancer activity of complexes 1-4 on human breast cancer cell line (MCF-7), human cervical cancer cell line (HeLa) and non-cancerous NIH-3T3 cell line exhibit moderate to excellent cytotoxic activity. It is also evident from IC50values that the complexes are more potent against MCF-7 cells than cisplatin. The superior activity of the complex 4 assumes that presence of electron donating methoxy substituent which makes the ring more reactive. Further, the morphological changes during cell death were investigated by Acridine Orange-Ethidium Bromide (AO-EB) and DAPI staining techniques, which confirm the complex 4 induces cell death only through apoptosis.
