Conjugated microporous polymers with chiral BINAP ligand built-in as efficient catalysts for asymmetric hydrogenation

A series of chiral conjugated microporous polymers (CMPs) based on the chiral (R)-BINAP ligand (BINAP-CMPs) were synthesized with tunable BET surface areas. These solid catalysts show high activities and enantioselectivities for the asymmetric hydrogenation of beta-keto esters after coordination with ruthenium species. Moreover, CMPs can realize spatial isolation. Through preventing the formation of dimers and trimers, BINAP-CMPs show much higher activity than BINAP for the Ir-catalyzed asymmetric hydrogenation of quinaldine.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 37366-09-9 is helpful to your research., Synthetic Route of 37366-09-9

Arene-ruthenium(II) acylpyrazolonato complexes: Apoptosis-promoting effects on human cancer cells

A series of ruthenium(II) arene complexes with the 4-(biphenyl-4-carbonyl)- 3-methyl-1-phenyl-5-pyrazolonate ligand, and related 1,3,5-triaza-7- phosphaadamantane (PTA) derivatives, has been synthesized. The compounds have been characterized by NMR and IR spectroscopy, ESI mass spectrometry, elemental analysis, and X-ray crystallography. Antiproliferative activity in four human cancer cell lines was determined by MTT assay, yielding dose- and cancer cell line-dependent IC50 values of 9-34 muM for three hexamethylbenzene-ruthenium complexes, whereas the other metal complexes were much less active. Apoptosis was the mechanism involved in the anticancer activity of such compounds. In fact, the hexamethylbenzene-ruthenium complexes activated caspase activity, with consequent DNA fragmentation, accumulation of pro-apoptotic proteins (p27, p53, p89 PARP fragments), and the concomitant down-regulation of antiapoptotic protein Bcl-2. Biosensor-based binding studies indicated that the ancillary ligands were critical in determining the DNA binding affinities, and competition binding experiments further characterized the nature of the interaction.

Effect of support type and synthesis conditions on the oxygen reduction activity of RuxSey catalyst prepared by the microwave polyol method

RuxSey nanoparticles supported on different carbon substrates were synthesized by microwave heating of ethylene glycol solutions of Ru(III) chloride and sodium selenite at different pH and Ru/Se mole ratios. The resulting catalysts were used for the electrochemical oxygen reduction reaction (ORR) in acidic solution. The electrochemical activity was highest for the supported catalyst synthesized at pH 8. Increasing the Se concentration of the catalyst up to 15 mol% increased the catalytic activity for the ORR; at this Se concentration, the activity of the catalyst was considerably higher than that observed for pure Ru catalyst synthesized at exactly the same conditions. The influence of the type of carbon support on the activity of the electrocatalyst was also investigated. Among the different supports, including carbon black (Vulcan XC-72R) (C1), and nanoporous carbons synthesized from resorcinol- (C2) and phloroglucinol-formaldehyde (C3) resins, the RuxSey catalyst supported on C3 exhibited highest activity for ORR.

An end-on-coordinated As4 tetrahedron

One time only: The reaction of [Cp*Ru(dppe)Cl] with the potent As4 transfer reagent [Ag(eta2-As4) 2]+[pftb]- leads to [Cp*Ru(dppe) (eta1-As4)]+[pftb]- with an unprecedented end-on-coordinated As4 tetrahedron. Reaction with a second cationic ruthenium complex fragment does not lead to a second end-on coordination but to the cleavage of one basal As-As bond. This behavior, which differs from its phosphorus analogues, is rationalized by DFT calculations. Copyright

Ruthenium(III) catalysed oxidation of gabapentin (neurontin) by diperiodatonickelate(IV) in aqueous alkaline medium: A kinetic and mechanistic study

The kinetics of Ru(III) catalysed oxidation of neuroleptic drug, gabapentin by diperiodatonickelate(IV) (DPN) in alkaline medium at 298 K and a constant ionic strength of 0.30 mol dm-3 was studied spectrophotometrically. The oxidation products are 1-(hydroxymethyl) cyclohexane acetic acid and Ni(II) which are identified by spectral studies. The stoichiometry of the reaction is 1:1 which is similar as in the case of absence of ruthenium(III). The oxidation reaction in alkaline medium has been shown to proceed via a Ru(III)-gabapentin complex, which further reacts with deprotonated form of DPN in a rate determining step, which is followed by other fast steps to give the products. The reaction constants involved in the different steps of the mechanism are calculated. The activation parameters with respect to slow step of the mechanism are computed and discussed and thermodynamic quantities are also determined. The catalytic constant (KC) was calculated at different temperatures. The probable active species of catalyst and oxidant have been identified.

Hole tunneling and hopping in a Ru(bpy)32+- phenothiazine dyad with a bridge derived from oligo-p-phenylene

A molecular dyad was synthesized in which a Ru(bpy)3 2+ (bpy = 2,2?-bipyridine) photosensitizer and a phenothiazine redox partner are bridged by a sequence of tetramethoxybenzene, p-dimethoxybenzene, and p-xylene units. Hole transfer from the oxidized metal complex to the phenothiazine was triggered using a flash-quench technique and investigated by transient absorption spectroscopy. Optical spectroscopic and electrochemical experiments performed on a suitable reference molecule in addition to the above-mentioned dyad lead to the conclusion that hole transfer from Ru(bpy)33+ to phenothiazine proceeds through a sequence of hopping and tunneling steps: Initial hole hopping from Ru(bpy) 33+ to the easily oxidizable tetramethoxybenzene unit is followed by tunneling through the barrier imposed by the p-dimethoxybenzene and p-xylene spacers. The overall charge transfer proceeds with a time constant of 41 ns, which compares favorably to a time constant of 1835 ns associated with equidistant hole tunneling between the same donor-acceptor couple bridged by three identical p-xylene units. The combined hopping/tunneling sequence thus leads to an acceleration of hole transfer by roughly a factor of 50 when compared to a pure tunneling mechanism.

Enantioselective synthesis of pyranonaphthoquinone antibiotics using a CBS reduction/cross-metathesis/oxa-Michael strategy

The enantioselective syntheses of deoxydihydrokalafungin (5), cis-deoxydihydrokalafungin (6) and deoxykalafungin (7) are reported. The strategy was based on 4 key reactions: (1) CBS reduction of prochiral ketone 10 to introduce chirality at C-1, (2) radical allylation of quinone 9a, (3) cross-metathesis of dimethoxynaphthalene 13 with methyl acrylate, and (4) intramolecular oxa-Michael addition of alcohol 8 to form the core naphthopyran ring system. This novel approach delivers naphthopyrans possessing the natural trans-stereochemistry observed in the pyranonaphthoquinone family of antibiotics.
