The cationic complexes have been isolated as their PF 6/SbF6 salts and characterized by FT-IR, UV-Vis, 1H NMR, Mass spectroscopic methods. X-ray crystallographic studies of some representative compounds revealed that typical piano-stool geometry around the metal center with a six-membered metallocycles in which thioether ligand acts as a N,N?-chelating ligand. Variation of bridging motifs of thioether ligands is revealed that formation of mono/dinuclear complexes. The L1 ligand yielded predominantly mononuclear compounds where as L2 and L3 yielded dinuclear compounds with trans and cis isomers, respectively.

Good things come in threes: A variety of beta-C-trisaccharides have been successfully synthesized by double ring-closing metathesis, which provides the products in excellent overall yield after functionalization of the newly formed double bonds (see scheme). The precursor olefin-enol ethers were prepared by Takai methylenation of the appropriate diesters.

Water oxidation catalysis by [(bpy)2(H2O)Ru-O-Ru(H2O)(bpy)2]4+ (Ru(III)(OH2)-O-Ru(III)(OH2)) complex was studied in a homogeneous aqueous solution (AS) as well as heterogeneous Nafion membrane (HM) using Ce(IV) oxidant. The initial O2 evolution rate, V(O2) (mol s-1) increased linearly at low complex concentrations under the excess Ce(IV) oxidant, showing that 4-electron water oxidation is catalyzed by one molecule of the complex. The intrinsic catalytic activities, k(O2) (s-1), in the AS and HM were 4.2 X 10-3 s-1 and 2.4 X 10-3 s-1, respectively. These values are much higher than those of well-known metal and metal oxide catalysts. Comparison of catalytic activity for various metal complexes and oxides is presented.

15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru, belongs to ruthenium-catalysts compound, is a common compound. In a patnet, once mentioned the new application about 15746-57-3, category: ruthenium-catalysts

[Ru(R-bpy)2Cl2] is an important starting material for the synthesis of [Ru(N6)]2+ complexes. During the conventional synthesis procedure of [Ru(R-bpy)2Cl2], yield loss of up to 50% occurs, due to the formation of the side product [Ru(R-bpy)2(CO)Cl]+. The CO ligand hinders further conversion to [Ru(N6)]2+. Here we describe a simple and efficient removement of the CO ligand followed by a complexation of a third chelating ligand generating [Ru(N6)]2+. Complete removal of the CO ligand and formation of an intermediate state is verified by ESI-MS spectrometry and IR spectroscopy. After complexation of the third chelating ligand bpy, pure [Ru(R-bpy)3]2+ was formed with complete conversion. Purity of [Ru(R-bpy)3]2+ was ensured by IR-, NMR-spectroscopy and MS spectrometry.

We report the first practical use of SF6as a fluorinating reagent in organic synthesis. Photoredox catalysis enables the in situ conversion of SF6, an inert gas, into an active fluorinating species by using visible light. Under these conditions, deoxyfluorination of allylic alcohols is effected with high chemoselectivity and is tolerant of a wide range of functional groups. Application of the methodology in a continuous-flow setup achieves comparable yields to those obtained with a batch setup, while providing drastically increased material throughput of valuable allylic fluoride products.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.172222-30-9, Name is Benzylidenebis(tricyclohexylphosphine)dichlororuthenium, molecular formula is C43H72Cl2P2Ru.

Ru- and Mo-based catalysts can be used in ring closing metathesis (RCM) reactions to synthesise cyclic phosphines protected as their borane complexes. The compatibility of the Schrock Mo-catalyst and the N-heterocyclic carbene Ru-catalysts with this class of substrates is particularly noteworthy as asymmetric RCM (ARCM) is now emerging as a new tool for the preparation of homochiral phosphines. One of the key results is that the Mo-catalyst allows the ring closure of the unprotected diallyphenylphosphine with 95% conversion.

The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 172222-30-9 is helpful to your research., Quality Control of: Benzylidenebis(tricyclohexylphosphine)dichlororuthenium
