A series of ruthenium catalysts has been screened in the self-metathesis of 1-dodecene with and without the addition of benzoquinones. Many of these catalysts demonstrated excellent selectivity and yields with as low as 10 ppm catalyst loading. Reactions have been conducted under decreased pressure or under argon bubbling, which caused a tremendous increase in yield and selectivity of the examined process. Copyright

Ruthenium-alkylidene-catalyzed cross-metathesis of a range of homologous alkenylamine salts provides expedient and high-yielding routes to commercially valuable polyamide monomers using a single catalyst, telescopic workup, and mild experimental conditions.

The multijet oscillating disk (MJOD) flow reactor is a relatively new technology for continuous flow synthesis. This technology is still under investigation as an all-round platform for flow synthesis. In this article, findings are disclosed from a project where a MJOD flow reactor rig (reactor volume of ?50 mL) was investigated as the reaction platform for ring closing metathesis and cross (self) metathesis reaction, using reaction mixture volumes down to only ?5 mL. The Hoveyda-Grubbs second-generation catalyst was used without an inert atmosphere. The results of the flow synthesis provided excellent selectivity and high yield. For comparison purposes, the syntheses conducted in the MJOD reactor were compared with similar literature experiments performed with other flow technologies and batch conditions.

A dicationic ruthenium-alkylidene complex [Ru(dmf)3(IMesH 2)(=CH-2-(2-PrO)-C6H4)][(BF4) 2] (1; IMesH2=1,3-dimesitylimidazolin-2-ylidene) has been prepared and used in continuous metathesis reactions by exploiting supported ionic-liquid phase (SILP) technology. For these purposes, ring-opening metathesis polymerization (ROMP)-derived monoliths were prepared from norborn-2-ene, tris(norborn-5-ene-2-ylmethyloxy)methylsilane, and [RuCl 2(PCy3)2(CHPh)] (Cy=cyclohexyl) in the presence of 2-propanol and toluene and surface grafted with norborn-5-en-2-ylmethyl-N,N, N-trimethylammonium tetrafluoroborate ([NBE-CH2-NMe 3][BF4]). Subsequent immobilization of the ionic liquid (IL), 1-butyl-2,3-dimethylimidazolium tetrafluoroborate ([BDMIM][BF 4]), containing ionic catalyst 1 created the SILP catalyst. The use of a second liquid transport phase, which contained the substrate and was immiscible with the IL, allowed continuous metathesis reactions to be realized. High turnover numbers (TONs) of up to 3700 obtained in organic solvents for the ring-closing metathesis (RCM) of, for example, N,N-diallyltrifluoroacetamide, diethyl diallylmalonate, diethyl di(methallyl)malonate, tert-butyl-N,N- diallylcarbamate, N,N-diallylacetamide, diphenyldiallylsilane, and 1,7-octadiene, as well as in the self-metathesis of methyl oleate, could be further increased by using biphasic conditions with [BDMIM][BF 4]/heptane. Under continuous SILP conditions, TONs up to 900 were observed. Due to the ionic character of the initiator, catalyst leaching into the transport phase was very low (<0.1 %). Finally, the IL can, together with decomposed catalyst, be removed from the monolithic support by flushing with methanol. Upon reloading with [BDMIM][BF4]/1, the recycled support material again qualified for utilization in continuous metathesis reactions.

Ruthenium-based metathesis catalysts immobilized on mesocellular siliceous foam (MCF) bearing large nanopores proved highly efficient and selective for macrocyclic ring-closing metathesis (RCM). Kinetic studies revealed that the homogeneous counterpart exhibited far higher activity that accounted for more oligomerization pathways and resulted in less macrocyclization products. Meanwhile, the immobilized catalysts showed lower conversion rates leading to higher yields of macrocyclic products in a given reaction time, with conversion rates and yields dependent upon pore size, catalyst loading density, and linker length. The macrocycle formations via RCM were accelerated by increasing the pore size and decreasing the catalyst loading density while retaining the comparably high yield. The catalysts immobilized on MCF, of which silica surface is rigid and pores are relatively large, showed high conversion rates and yields compared with an analogue immobilized on TentaGel resins, of which backbone becomes flexible upon swelling in the reaction medium. It is noteworthy that the selectivity for the macrocyclic RCM can be significantly improved by tuning the catalyst initiation rates via immobilization onto the support materials in which well-defined three-dimentional network of large nanopores are deployed.

Disclosed are improved methods for conducting metathesis utilizing polyunsaturated fatty acid compositions (e.g., polyunsaturated fatty acid polyol esters, polyunsaturated fatty acids, polyunsaturated fatty esters, and mixtures), such as those found in naturally occurring oils and fats, as the starting material. The inventive methods involve hydrogenation of polyunsaturated fatty acid compositions prior to metathesis, thereby providing partially-hydrogenation compositions having a relatively higher amount of monounsaturated fatty acid species. The partially hydrogenated composition can then be subjected to metathesis to provide a metathesis product composition containing industrially useful compounds.

Marinomycins A-C (1-3), and their monomeric analogues monomarinomycin A (m-1) and iso-monomarinomycin A (m-2), were synthesized by a convergent strategy from key building blocks ketophosphonate 5, aldehyde 6, and dienyl bromide carboxylic acid 7. The first attempt to construct marinomycin A [1, convertible to marinomycins B (2) and C (3) by light] by direct Suzuki-type dimerization/ cyclization of boronic acid dienyl bromide 4 led to premature ring closure to afford, after global desilylation, monomarinomycin A (m-1) and iso-monomarinomycin A (m-2) in good yield and only small amounts (?2%) of the desired product. A subsequent stepwise approach based on Suzuki-type couplings improved considerably the overall yield of marinomycin A (1), and hence of marinomycins B (2) and C (3). Alternative direct dimerization approaches based on the Stille and Heck coupling reactions also led to monomarinomycins A (m-1 and m-2), but failed to deliver useful amounts of marinomycin A (1).

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 301224-40-8 is helpful to your research., Application of 301224-40-8

The invention is directed to ruthenium-based metathesis catalysts of the Grubbs-Hoveyda type. The new 2-aryloxy-substituted ruthenium catalysts described herein reveal rapid initiation behavior. Further, the corresponding styrene-based precursor compounds are disclosed. The catalysts are prepared in a cross-metathesis reaction starting from styrene-based precursors which can be prepared in a cost- effective manner. The new Grubbs-Hoveyda type catalysts are suitable to catalyze ring- closing metathesis (RCM), cross metathesis (CM) and ring- opening metathesis polymerization (ROMP). Low catalyst loadings are necessary to convert a wide range of substrates including more complex and critical substrates via metathesis reactions at low to moderate temperatures in high yields within short reaction times.
