The complex [Ru(CCCN)(dppe)Cp*] (1) is readily obtained (ca. 70%) from the sequential reaction of [Ru(CCH2)(dppe)Cp*]PF 6 with nBuLi and phenyl cyanate. The complex behaves as a typical transition metal acetylide upon reaction with tetracyanoethene, affording a metallated pentacyanobutadiene. Complex 1 is a useful metalloligand, and its reactions with [W(thf)(CO)5], [RuCl(PPh3) 2Cp], [RuCl(dppe)Cp*] or cis-[RuCl2(dppe) 2] all afforded products featuring the M-CCCN-M? motif, for which ground state structures indicate a degree of polarisation. Electrochemical and spectroelectrochemical studies reveal moderate interactions between the metal centres in the 35-electron dications [{Cp*(dppe)Ru}(mu-CCCN) {RuL2Cp?}]2+ (RuL2Cp? = Ru(PPh 3)2Cp, Ru(dppe)Cp*).

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.Recommanded Product: 32993-05-8, you can also check out more blogs about32993-05-8

(Chemical Presented) The unique 16-membered macrolide (+)-exiguolide (1) was the target of a total synthesis featuring radical and Prins cyclizations of beta-alkoxyacrylates, along with ring-closing olefin metathesis. The structure incorporates two cis-2,6-disubstituted oxane rings where one of the rings has an exocyclic enoate group. The successful synthesis of 1, isolated from a marine sponge, led to the unambiguous determination of its absolute stereochemistry.

A sixteen-step synthesis of the twelve-membered macrolide (-)-cladospolide B (2) from the microbially-derived cis-1,2-dihydrocatechol 5 is described. Pivotal steps include the ring-closing metathesis (RCM) of diene 12 to give the ten-membered lactone 13 together with small amounts of the head-to-tail and head-to-head dimers 14 and 15, respectively. The saturated lactol 19 derived from compounds 13 and 14 readily participates in a Wadsworth-Horner-Emmons reaction to give the E-configured alpha,beta-unsaturated ester 20. This last compound is then converted, through application of a Yamaguchi lactonisation reaction on the derived acid 22, into the macrolide 23 which, upon removal of the bis-acetal protecting group, affords compound 24, the E-isomer of target 2. Irradiation of a benzene solution of compound 24 results in its partial photoisomerisation to (-)-cladospolide B (2). The Royal Society of Chemistry 2005.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer, molecular formula is C12H12Cl4Ru2. In a Article，once mentioned of 37366-09-9, category: ruthenium-catalysts

Novel multidentate pyridyl-aminophosphinite (L1) and pyridyl-phosphoramidite (L2) ligands of N^P^P^N-donor system have been synthesized via a series of simple steps. The ligands are symmetrical and as a result, their reactions with [Ru(p-cymene)Cl2]2 and [Ru(benzene)Cl2]2 lead to the formation of four monodentate bimetallic complexes (1?4) that retain the symmetry of the ligands. Meso and racemic mixtures (rac) of bidentate bimetallic complexes 5?8 were formed from the monodentate complexes through coordination of the pyridine nitrogen atoms to the two metal centers. The isomerism occurs at each metal center, which was evidenced by 31P{1H}, 1H NMR spectroscopy and single-crystal X-ray diffraction. The complexes were active towards hydrogenation of levulinic acid (LA) to gamma-valerolactone (GVL) using formic acid as the hydrogen source. The complexes are active at relatively low temperatures and are able to perform the hydrogenation in the absence of any additional solvent apart from the reagents to give high TON of 3 600. The catalysts are recyclable up to the fourth cycle, following which 20 % loss of activity is seen.

The complex [(eta5-MeC5H4)Ru(DPVP)2(CH3 CN)]PF6 (4) (DPVP = Ph2PCH=CH2) loses CH3CN under vacuum to produce the phosphaallyl complex [(eta5-MeC5H4)Ru(eta1-DPVP)( eta3-DPVP)]PF6 (6) and reacts with Me3SiC?CH and PhC?CH in CH2Cl2-CH3OH solutions to form the methoxymethylcarbene [(eta5-MeC5H4)(DPVP)2Ru=C(OCH 3)(CH3)]PF6 (7) and the carbonyl complex [(eta5-MeC5H4)Ru(DPVP)2(CO)]PF 6 (8), respectively. In contrast [(eta5-MeC5H4)Ru(DPVP)(CO)(CH3CN)] PF6 (15) does not lose CH3CN to form a phosphaallyl complex. The structures of the complexes described herein have been deduced from elemental analyses, infrared spectroscopy, 1H, 13C{1H}, 1H NOE, where appropriate by 31P{1H} NMR spectroscopy and in eight cases by X-ray crystallography.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.114615-82-6, Name is Tetrapropylammonium perruthenate, molecular formula is C12H28NO4Ru. In a Article，once mentioned of 114615-82-6, SDS of cas: 114615-82-6

2-Propanol is oxidized by tetrapropylammonium perruthenate (TPAP) in a reaction that is second order in TPAP and first order in 2-propanol. One of the products, believed to be ruthenium dioxide, is an effective catalyst for the reaction, making it an autocatalytic process. The rate of oxidation is relatively insensitive to the presence of substituents. Primary kinetic deuterium isotope effects are observed when either the hydroxyl or the alpha hydrogen is replaced by deuterium. The only product obtained from the oxidation of cyclobutanol is cyclobutanone, indicating that the reaction is a two-electron process. Tetrahydrofuran is oxidized at a rate that is several orders of magnitude slower than that observed for 2-propanol, suggesting that the reaction of TPAP with alcohols may be initiated by formation of perruthenate esters. A tentative mechanism consistent with these observations is proposed.

A series of ruthenium olefin metathesis catalysts bearing N-heterocycliccarbene (NHC) ligands with varying degrees of backbone and N-aryl subst itution have been prepared. These complexes show greater resistance to decomposition through C-H activation of the N-aryl group, resulting in increased catalyst lifetimes. This work has utilized robotic technology toexamine the activity and stability of each catalyst in metathesis, prov iding insights into the relationship between ligand architecture and enhanced efficiency. The development of this robotic methodology has also shown that, under optimized conditions, catalyst loadings as low as 25 ppm can lead to 100percent conversion in the ring-closing metathesis of diethyl diallylmalonate.
