A much improved synthesis for the carbagerma-closo-dodecaborate anion [GeCB10H11]- is described in the form of [Bu3NH][GeCB10H11] (1). In reactions with transition metal electrophiles, three transition metal complexes {[Bu 3NH][(C6H6)Ru(Cl)2(GeCB 10H11)] (2), [Bu3NH][Cp*Ir(Cl)(GeCB 10H11)2] (3) and [Me3NH][(PPh 3)2Ir(CO)(GeCB10H11)2] (4)} with metal-germanium bonds were synthesized. The carbagermaborate anion, in the form of the salt [Et3NH][GeCB10H11], and the coordination compounds 2-4 were structurally characterized by single-crystal X-ray diffraction. Computations were carried out for the anions in 1-4 to aid NMR assignments. An improved synthesis of carbagerma-closo-dodecaborate is presented. Coordination compounds with this type of germylene ligands are structurally characterized, and the ligand properties are discussed by using the results of quantum chemical calculations. Copyright

A new flexible approach for the stereoselective synthesis of substituted 1H-pyrrol-2(5H)-ones and 3,6-dihydro-1H-pyridin-2-ones has been developed. The general strategy employed the stereoselective reduction of a series of alpha,beta-unsaturated ketones under chelation control to give the corresponding allylic alcohols. Overman rearrangement to install the key C-N bond followed by conversion to either prop-2-enoyl or but-3-enoyl derivatives and a ring closing metathesis reaction gave the target unsaturated gamma- and delta-lactams. The synthetic utility of these compounds as building blocks was demonstrated by the preparation of the N-Boc derivative of (-)-coniine.

An efficient method for the preparation of new alpha-CF3 alpha-amino acid 1,7-enynes that contain electron-donating and electron-withdrawing groups on the triple bond has been developed that proceeds through a Sonogashira-type coupling reaction. The ring-closing enyne methathesis (RCEYM) of the obtained 1,7-enynes with commercially available Grubbs and Hoveyda catalysts provides access to a series of new cyclic alpha-amino acids. The latter compounds that contain the 1,3-diene moiety are attractive building blocks for the construction of trifluoromethylated polycyclic systems.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.10049-08-8, Name is Ruthenium(III) chloride, molecular formula is Cl3Ru. In a Article，once mentioned of 10049-08-8, HPLC of Formula: Cl3Ru

The ruthenium(III) chloride catalyzed oxidation of butanone-2 and pentanone-3 by aqueous cerium(IV) was found to be first order with respect to ketone concentration.The rate is inversely proportional to the square of sulfuric acid concentration but reaction velocity shows first-order behaviour at lower concentrations.The linear dependence of the reaction rate at lower ruthenium(III) concentrations tends toward zero order at higher concentrations.These data suggest that the oxidation of these ketones proceeds via the formation of an activated complex between ruthenium(III) and protonated ketones which rapidly decomposes, followed by a fast reaction between ruthenium(III) hydride and the cerium(IV) species.

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.HPLC of Formula: Cl3Ru, you can also check out more blogs about10049-08-8

In this review, we reported on the Proline-chimeras characterized by resembling the skeleton of Alanine (Alanine-Proline chimeras). The synthetic approaches were classified according to the position of the methyl group on the pyrrolidine ring. Moreover, the synthesis of pyroglutamic acid derivatives will be discussed due to its importance as building block and chiral pool in the asymmetric synthesis of numerous bioactive compounds. The present review will be focused on the chemical syntheses of mono-methyl substituted proline derivatives, including the contribution to the literature from 2004 to 2016.

The removal of sulfur (as H2S) from organosulfur species in petroleum feedstocks (hydrodesulfurization, HDS) is carried out on an enormous scale by using heterogeneous catalysts based on MoS2 (usually doped with Co). Partially hydrogenated thiophenes are postulated intermediates in the MoS2-catalyzed hydrodesulfurization of thiophene. The present contribution describes new molecular models for the proposed active sites in HDS catalysis. The models are derived from a mixed-ligand (push-pull) molybdenum trisdithiolene {[Mo(tfd)2(bdt)]; tfd = S2C 2(CF3)2, bdt = S2C6H 4}: selective intraligand alkyne binding converts the bdt group to a labile Mo-chelating benzodithiin, which can be substituted with a variety of weak donor ligands. The complexes [Mo(tfd)2-(dht)2] and [Mo(tfd)2(tht)2] (dht = 2,5-dihydrothiophene; tht =tetrahydrothiophene) were synthesized and crystallographically characterized. The Mo(tfd)2 substructures closely resemble the presumed active site in MoS2 HDS catalysts. The coordination geometries at molybdenum are approximately trigonal prismatic, and the metal bears two strongly bound dithiolene (tfd) groups and two comparatively weakly bound thioether ligands (dht or tht). Competitive binding experiments establish that tht binds more strongly to the Mo center than dht (Keq = 6.5±0.5). Preliminary reactivity studies reveal that [Mo(tfd)2(dht) 2] decomposes to [Mo(tfd)3], thiophene, and unidentified species upon heating. Further, [Mo(tfd)2(tht)2] induces the isomerization of 1,4-cyclohexadiene to 1,3-cyclohexadiene at elevated temperatures.
