Ruthenium catalysts

A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru.

Synthesis and excited-state propertdies of a novel ruthenium nucleoside: 5-[Ru(bpy)2(4-m-4?-pa-bpy)]2+-2?-deoxyuridine

The synthesis and photophysical properties of a novel ruthenium-modified nucleoside are reported. The key synthetic step to 5-[Ru(bpy)2(4-m-4?-pa-bpy)]2+-2?-deoxyuridine involves the Pd(0)-catalyzed cross-coupling of a propargylamine-derivatized Ru(bpy)32+ and 3?,5?-dibenzoyloxy-2?-deoxy-5-iodouridine. The long-lived 3MLCT excited state (1300 ns) of 5-[Ru(bpy)2(4-m-4?-pa-bpy)]2+-2?-deoxyuridine has an emission maximum centered at 640 nm. Step-scan Fourier transform infrared (S2FTIR) time-resolved spectroscopy reveals the excited-state electron to be localized on the modified bipyridine with the excited-state dipole oriented toward the 2?-deoxyuridine.

Expeditious entry to the chamigrane endoperoxide family of natural products

Several members of the recently reported peroxy chamigrane family of natural products were synthesized via a distereoselective route with a novel facial-selective epoxidation of a spiroundecadiene, a facile epoxide rearrangement, and a Co(II)-mediated silylperoxidation as the key steps. Adaptation of the diastereoselective route to an enantioselective one is also illustrated.

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.COA of Formula: C46H65Cl2N2PRu, you can also check out more blogs about246047-72-3

Substituted N and O heterocycles have been synthesized by the cycloisomerization of dienes using a ruthenium-carbene catalyst. The products obtained with and without trimethylsilyl vinyl ether differ (see scheme, Cy = cyclohexyl, Mes = 2,4,6-trimethylphenyl, Ts = p-toluenesulfonyl).

Covalent heterodyads of synthetic chlorophyll derivatives linked with linear rigid substituents at the 20-positions constructing photoexcited energy transfer systems

Chlorophyll and bacteriochlorophyll pigments are important porphyrinoids, which play key roles in light absorption, energy migration/transfer, and electron transfer in natural photosynthesis. Dyads of such pigments have attracted much attention from the viewpoints of mimicking photosynthetic light-harvesting and charge-separating systems. In this study, we report the synthesis and optical properties of heterodyads of zinc chlorin and free-base bacteriochlorin covalently linked by linear rigid substituents at the 20-position, which were prepared from naturally occurring chlorophyll-a. A free-base bacteriochlorin moiety accepted the singlet excitation energy from the zinc chlorin in the heterodyads. In the co-aggregate systems of heterodyads with chlorosomal self-assemblies, the latter transfers the singlet excitation energy to the bacteriochlorin moiety of the former, which are useful for artificial chlorosomal supramolecular light-harvesting systems.

Iridium and ruthenium catalyzed syntheses, hydroborations, and metathesis reactions of alkenyl-decaboranes

The selective syntheses of new classes of 6,9-dialkenyl- and 6-alkenyl-decaboranes and 6-alkyl-9-alkenyl-decaboranes have been achieved via iridium and ruthenium catalyzed decaborane and 6-alkyl-decaborane alkyne-hydroborations. Reactions employing [Cp*IrCl2] 2 and [RuCl2(p-cymene)]2 precatalysts gave beta-E-alkenyl-decaboranes, while the corresponding reactions with [RuI 2(p-cymene)]2 gave the alpha-alkenyl-decaborane isomers, with the differences in product selectivity suggesting quite different mechanistic steps for the catalysts. The alkenyl-decaboranes were easily converted to other useful derivatives, including coupled-cage and functionally substituted compounds, via iridium-catalyzed hydroborations and ruthenium-catalyzed homo and cross olefin-metathesis reactions.

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.

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.
