Reference of 246047-72-3, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 246047-72-3, Name is (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, molecular formula is C46H65Cl2N2PRu.

Three novel ruthenium(II) complexes, RuX2(IMesH 2)[N,N-diethyl-N?-(2-benzylidene)triazene] [IMesH2 = 1,3-dimesitylimidazolin-2-ylidene; X = Cl- (2), CF 3COO- (3), C6F5COO- (4)] are described. Single-crystal X-ray structure analysis of compounds 2-4 revealed that the triazene ligand exists in the trans form and that the aryl-connected nitrogen atom of the triazene binds to the ruthenium atom to form a five-membered chelate ring. Compounds 2-4 were applied to the UV-induced ring-opening metathesis polymerization (ROMP) of cis-cyclooctene (5) and dicyclopentadiene (6). Whereas all three precatalysts show pronounced thermal latency in the presence of 5 or 6, only compound 2 displays significant photo-ROMP activity. The photoreactivity of precatalysts 2-4, which decreases with increasing electron-withdrawing character and with decreasing pK a of the X groups, is discussed and correlated with the X-ray data of 2-4, with low-temperature 1H NMR measurements as well as with cyclovoltammetric measurements. Three novel complexes, RuX 2(IMesH2)[N,N-diethyl-N?-(2-benzylidene)triazene] [IMesH2 = 1,3-dimesitylimidazolin-2-ylidene; X = Cl- (2), CF3COO- (3), C6F5COO- (4)] are used in the UV-induced ring-opening metathesis polymerization (ROMP) of cis-cyclooctene and dicyclopentadiene. The photoactivity of 2-4 decreases with increasing electron-withdrawing character and with decreasing pKa of the X groups. Copyright

The potential expansion of the variety of catalytic methods for carbon?carbon bond formation is explored in many research centers all over the world. In this work, we describe very precise and controlled catalytic transformations as useful tools for the synthesis of new trans-pi-conjugated molecular organic compounds. The combination of Suzuki?Miyaura coupling and cross-metathesis reactions is established as a simple and efficient method for the design of new (E)-stilbenes in the presence of well-defined transition-metal catalysts at 0.0001?1 % loadings. All of the desired products are isolated in good-to-excellent yields (up to 96 % isolated yield) with high purity.

A rapid and diastereoselective synthesis of highly substituted aminobicyclo[4.3.0]nonanes and bicyclo[4.4.0]decanes from alkyne derived allylic alcohols has been developed using a one-pot multi-bond forming tandem catalytic process. Overman rearrangement of the allylic trichloroacetimidates was followed by a ring closing enyne metathesis/cross metathesis sequence of reactions, in which both steps were catalysed by Grubbs second generation catalyst. The resulting exo-diene was then subjected to a hydrogen bonding directed Diels?Alder reaction forming an endo-adduct as a single diastereomer. Variation of the cross metathesis partner and dienophile allowed examination of the scope of this one-pot process and the preparation of a diverse series of highly substituted polycyclic scaffolds.

Hoveyda-Grubbs catalyst in combination with BF3·OEt2 efficiently promotes tandem cross metathesis intramolecular aza-Michael reaction between enones and unsaturated carbamates resulting in the creation of beta-amino carbonyl units. The use of microwave irradiation dramatically accelerates the process, enhancing the synthetic utility of this methodology for the preparation of these types of derivatives. When enantiomerically enriched ?-branched amines were used as starting materials, the process was also very efficient, although with modest selectivity in the newly created stereocenter. The use of microwave irradiation led to an interesting effect, inverting the selectivity in the addition process. Copyright

New aryloxybenzylidene ruthenium chelates behave like a promising latent catalyst of olefin metathesis. The catalysts are characterised by substantial stability and catalytic inactivity in their dormant forms and a dramatic increase in activity after addition of a solution of HCl in ether. The mechanism of activation involves protonation of the phenoxide and the formation of a highly catalytically active hydroxybenzylidene ruthenium chelate. Ruthenium aryloxybenzylidene complexes have been synthesised and proved to behave like latent catalysts of olefin metathesis. The mechanism of chemical activation by HCl involves the formation of an isolable catalytically active hydroxybenzylidene complex. Copyright

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.name: (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium, you can also check out more blogs about246047-72-3

A new hybrid microwave (MW) and ultrasound (US)-assisted reactor concept was investigated. The 2.45 GHz microwaves were delivered by a semiconductor generator via a coaxial cable to a monomode Transverse Electric (TE) microwave resonant cavity within which the reactor was placed; the US (25 kHz) were delivered at the bottom of the TE cavity via a novel designed sonotrode consisting of a detachable metallic plate-probe (indirect sonication). The semiconductor microwave generator helped to optimize the absorbed energy via its automatic frequency tuning function. The dual MW/US device allowed the use of both technologies separately or in a simultaneous combined manner. The ring-closing metathesis of diethyl diallyl malonate in glycerol micellar conditions was studied as an example using this novel hybrid technology. The results were compared with those obtained when microwaves or ultrasound were applied individually. Various benzylidene-, indenylidene- and Hoveyda-Grubbs-type catalysts were screened. The novel reactor for combined MW/US irradiation showed beneficial effects on the outcome of the reaction.

Two different stereoselective routes for the synthesis of Jaspine B and its C2 epimer are presented here, starting from easily available Garner aldehyde. The key synthetic steps involved iodocyclization, organocuprate addition, HWE olefination, regioselective alpha-tosylation and cross metathesis reaction. This is the first report to synthesize Jaspine B involving iodocyclization. The Royal Society of Chemistry 2013.

The tandem dienyne ring-closing metathesis of alkynyl silaketals containing two tethered olefins was achieved with second generation Grubbs NHC-ruthenium carbene complex to provide bicyclic siloxanes in good to excellent yield. Silaketals synthesized from homoallylic or bishomoallylic alcohols via base-catalyzed alcoholysis of trialkynylsilanes were well tolerated in the metathesis process and generated ring systems of various sizes. Removal of the silicon tether was achieved through protodesilylation with fluoride to afford stereochemically defined (1E,3Z)-dienes.
