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. 32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), molecular formula is C41H35ClP2Ru.

The first spiro cyclic phosphazene containing a nitrile pendant coordinating group, N3P3(O2C12H8) 2(OC6H4CH2CN)2 (1), has been synthesized by the reaction of the spiro cyclophosphazene N3P3(O2C12H8) 2Cl2 with HOC6H4CH2CN and K2CO3 in acetone. The spiro nitrile derivative 1 reacted with CpFe(dppe)I and with CpRu(PPh3)2Cl in the presence of NH4PF6 in CH3OH as solvent to give the complexes {[CpFe(dppe)]2(NCCH2C6H4O) 2N3P3(O2C12H 8)2}(PF6)2 (2) and {[CpRu(PPh3)2]2(NCCH2C 6H4O)2N3P3(O 2C12H8)2}(PF6) 2 (3), respectively. The spectroscopic results indicate that the spiro nitrile derivative behaves like their nitrile ligands. These results have been confirmed by extended Hueckel molecular orbital calculations which have been carried out on the model complexes [CpFe(PH3)2NCCH3]+ (4) and [CpFe(PH3)2(NC-CH2-C6H 4-O)(HO)5N3P3]+ (5). Two metal-to-ligand charge-transfer bands unprecedented in iron-nitrile complexes were observed in the electronic spectrum, as was predicted by the theoretical calculations. The electronic structures of complexes are discussed.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru.

A new Ru(II) complex is described which serves as a luminescence lifetime-based sensor for fluoride and cyanide anions (KF = 640 000 mol-1, KCN = 430 000 mol-1). This chromophore displays observable changes in its UV-vis and steady-state luminescence spectra upon cyanide binding. Prior to cyanide addition, this complex exhibits a single-exponential lifetime (tau = 377 ± 20 ns). With increasing cyanide concentrations, the intensity decays are composed of two exponentials: long tau (320-370 ns) and short tau (13-17 ns). The average lifetimes shorten as a function of cyanide concentration since the fractional intensity shifts from an initial dominant long lifetime component to the short lifetime component. This work represents the first example of a direct method for the luminescence lifetime-based sensing of anions. Copyright

Seven chain-like trinuclear complexes containing cis-configured central Fe(CN)2 or Fe(NC)2 units attached to two peripheral organometallic units containing Fe, Ru, Cr, or Mn have been synthesized. IR spectra and cyclic voltammograms allow assessment of their electronic situation. Chemical two-electron oxidations were possible for the complexes with Fe(CN-Fe)2 backbones. The oxidized complexes give rise to metal-metal charge transfer bands indicative of significant metal-metal interactions. Their magnetic susceptibilities indicate the absence of magnetic coupling between their two unpaired electrons.

A process has been invented for the oxygenation of cyclic ethers. General problems in the process are the use of expensive and toxic oxidants, low TONs (turnover numbers), low selectivity and working at elevated temperatures (energy costs). These problems were solved by employing appropriate organometallic catalyst precursors. Using lnd(CO)3Mo-Ru(CO)2Cp, Cp(CO)3Mo-Ru(CO)2Cp and Cp(CO)2Ru-Ru(CO)2Cp or other ruthenium compounds, the aerobic oxidation of tetrahydrofurane (THF) proceeds at room temperature and produces selectively gamma-butyrolactone. Use of the catalysts yields replacement of stoichiometric, toxic co-oxidants by cheap air oxygen, working at room temperature, high selectivity, high TONs and overall formulation of green chemistry which is applicable to cyclic ethers: formula (I) The invented process satisfies the urge for green chemistry by using cheap air oxygen in a catalytic process with unlimited catalyst lifetime and plain water as the side product. Functionalised lactones will be available from corresponding ethers.

Acridine derivatives constitute a class of compounds that are being intensively studied as potential anticancer drugs. Acridines are well-known for their high cytotoxic activity; however, their clinical application is limited or even excluded because of side effects. Numerous synthetic methods are focused on the preparation of target acridine skeletons or modifications of naturally occurring compounds, such as acridone alkaloids, that exhibit promising anticancer activities. They have been examined in vitro and in vivo to test their importance for cancer treatment and to establish the mechanism of action at both the molecular and cellular level, which is necessary for the optimization of their properties so that they are suitable in chemotherapy. In this article, we review natural and synthetic acridine/acridone analogs, their application as anticancer drugs and methods for their preparation. Copyright

Reference of 301224-40-8, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.301224-40-8, Name is (1,3-Dimesitylimidazolidin-2-ylidene)(2-isopropoxybenzylidene)ruthenium(VI) chloride, molecular formula is C31H38Cl2N2ORu. In a patent, introducing its new discovery.

A concise synthesis of spiropyrrolidines and spiropiperidines has been developed. The approach employs a ruthenium-alkylidene-catalysed cross-metathesis reaction of enantiopure N-protected allylglycine with methylenecycloalkanes. The resultant alkene intermediates can then undergo a tandem acid-catalysed cyclisation to form spiropyrrolidines. Ring expansion of the spiropyrrolidine system, via an aziridinium intermediate, grants access to the homologous spiropiperidine ring system with excellent stereoretention.
