The article was titled 《Formic Acid Dehydrogenation for Hydrogen Production Promoted by Grubbs and Hoveyda-Grubbs Catalysts》, and you may find the article in Chinese Journal of Chemistry.Formula: C43H72Cl2P2Ru The information in the text is summarized as follows:

Main observation and conclusion : In this work, we screened three Grubbs catalysts and two Hoveyda-Grubbs catalysts for the production of H2 by dehydrogenation of formic acid (FA). The best results were achieved with the use of a first-generation Hoveyda-Grubbs catalyst. With a catalyst loading of mere 0.5μmol, a maximum TON of 36356 was obtained within 3 h. Two key intermediates were identified by using 1H NMR and high-resolution electrospray ionization mass spectroscopy (HRESI-MS), based on which a mechanism possibly responsible for the observed catalysis was proposed.Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9Formula: C43H72Cl2P2Ru) was used in this study.

Recommanded Product: Benzylidenebis(tricyclohexylphosphine)dichlororuthenium And the article was included in ACS Macro Letters in 2020. The article conveys some information:

In this work, a simple method is reported for control over initiation in frontal ring-opening metathesis polymerization (FROMP). This noncontact approach uses 375 nm light to excite Grubbs’ second-generation catalyst in the presence of a phosphite inhibitor. Photoinitiated FROMP of dicyclopentadiene (DCPD) displays a similar cure profile to that of its thermally initiated counterpart, yielding a robust polymer with high glass transition temperature Furthermore, this system is applied to enhance reaction rates in conventional ring-closing metathesis reactions.

《Intramolecular alkene-alkyne metathesis and 1,4-cis-hydrogenation as a stereocontrolled route to compounds with exocyclic double bonds》 was written by Vasil’ev, A. A.; Engman, L.; Serebryakov, E. P.. Category: chlorides-buliding-blocks And the article was included in Russian Chemical Bulletin in 2020. The article conveys some information:

A (propargyl)butenylmalonate I underwent chemoselective ring-closing enyne metathesis in the presence of the first-generation Grubbs metathesis catalyst followed by diastereoselective hydrogenation in the presence of (η6-naphthalene)Cr(CO)3 to yield the (E)-ethylidenecyclohexanedicarboxylate II. Sequential ring-closing enyne metathesis and stereoselective hydrogenation is thus validated in a model system for the diastereoselective preparation of cyclic compounds with exocyclic alkenes.

《Ru-Catalyzed cascade reaction of α,ω-alkynoic acids and arylethylamines towards the synthesis of aryl-fused heterocycles》 was published in Organic Chemistry Frontiers in 2020. These research results belong to Zheng, Yinying; Liu, Jiami; Lei, Xinsheng. COA of Formula: C43H72Cl2P2Ru The article mentions the following:

A simple, efficient and mild method for the preparation of aryl-fused heterocycles was developed using α,ω-alkynoic acids and arylethylamines. One of Grubbs’ ruthenium carbenes was able to catalyze the formation of exocyclic enol lactones from α,ω-alkynoic acids, which subsequently underwent aminolysis and N-acyl iminium ion formation/cyclization with arylethylamines in the presence of TFA, affording one kind of “”drug-privileged”” scaffold. Demonstrated with high functional group tolerance, this new cascade reaction endowed the Grubbs’ ruthenium carbene with a new synthetic utility beyond routine olefin metathesis.

The article was titled 《A Fischer-Type Ruthenium Carbene Complex as a Metathesis Catalyst for the Synthesis of Enol Ethers》.Product Details of 172222-30-9 The article contains the following contents:

The Grubbs G-I or G-II catalyst gives the ruthenium ethoxy carbene complex, which catalyzes ring-opening cross metathesis (ROCM) of a strained cyclic alkene to give a diene where one of the two alkene moieties in the product contains an ethoxy substituent. No polymeric products are detected. Hydrocarbons such as parent norbornene or substituted cyclopropenes can proceed with the reaction smoothly. Tertiary amines, N-alkylimides, esters, and aryl or alkyl bromides remain intact under the reaction conditions. In addition to vinyl ethers, vinylic esters can also be used. The time required to reach a 50% yield of the ROCM product t50 varies from 0.01 to 140 h depending on the strain and nucleophilicity of the double bond. Anchimeric participation of an electron-rich group would result in significant enhancement of the reactivity, and the t50 could be as short as several minutes. A similar substrate without such a neighboring group shows a much slower rate. An exo-norborne derivative reacts much faster than the corresponding endo-isomer. Alkenes with poor nucleophilicity are less favored for the ROCM process, so is less strained cyclooctene.

Reference of Benzylidenebis(tricyclohexylphosphine)dichlororutheniumIn 2022 ,《Olefin cross-metathesis of polynorbornene with polypentenamer: New norbornene-cyclopentene multiblock copolymers》 appeared in European Polymer Journal. The author of the article were Denisova, Yulia I.; Zhigarev, Vsevolod A.; Gringolts, Maria L.; Shandryuk, Georgiy A.; Peregudov, Alexander S.; Finkelshtein, Eugene Sh.; Kudryavtsev, Yaroslav V.. The article conveys some information:

Statistical multiblock copolymers of norbornene (NB) and cyclopentene (CP) with different compositions and average block lengths are synthesized via the metathesis of polynorbornene (PNB) with polypentenamer (PCP) mediated by Grubbs’ catalysts of the 1st (G1) and 2nd (G2) generations. Interest in the copolymerization of NB and CP is dictated by the attractive properties of their homopolymers, whereas its realization is hampered by the mismatch in their metathesis polymerization activities. This difficulty can be circumvented by starting from the homopolymers, which are well-known industrial products. Our study demonstrates that the interaction of PNB with PCP in dilute solutions at room temperature in the presence of G1 leads to the copolymers with short CP blocks of 1-3 units separating longer NB blocks. In situ 1H NMR monitoring of the process reveals nearly full depolymerization of PCP via the ring-closing intramol. metathesis and the formation of NB-CP copolymers presumably via the interaction of CP with PNB. The depolymerization can be suppressed by increasing the concentration of reacting polymers and replacing G1 with more active G2. Under these conditions, the cross-metathesis of PNB with PCP results in the multiblock NB-CP copolymers with composition close to that of the initial homopolymer mixture, but short blocks of the both comonomers. A copolymer with longer blocks that can inherit properties of the parent homopolymers is obtained by decreasing the reaction temperature to 5°C. Addnl. information about the structure of NB-CP copolymers is obtained via their hydrogenation followed by spectral and thermal characterization. Thus, the macromol. cross-metathesis of unsaturated polymers appears to be a versatile method to synthesize copolymers with different backbone structures that are hard to reach by other methods.

《Mn3O4/p(DCPD)HIPE nanocomposites as an efficient catalyst for oxidative degradation of phenol》 was written by Yesil, Rabia; Cetinkaya, Sevil. Category: chlorides-buliding-blocks And the article was included in Journal of Nanoparticle Research in 2020. The article conveys some information:

The increase in the amount of wastewater containing organic pollutants in various industrial processes creates serious problems for the environment. Sulfate radical-based advanced oxidation process (AOP) is an effective route to remove pollutants from wastewater. However, designing a new nano-based catalyst to generate sulfate radicals is an important factor for the AOP. For this vision, porous trimanganese tetraoxide-polydicyclopentadiene (Mn3O4/pDCPD) nanocomposite, having an open-cell structure, was successfully designed via high internal phase emulsion (HIPE) and ring-opening metathesis polymerization (ROMP) approaches. The effect of Mn3O4 nanoparticle concentration on the structure was investigated, and the resulting Mn3O4/p(DCPD)HIPE nanocomposites were fully characterized by FT-IR, XRD, FE-SEM, TEM, solid-state 13C CPMAS NMR, DSC, and TGA anal. The selected nanocomposite containing 5 wt% of Mn3O4 was used as a model catalyst to mediate the heterogeneous oxidation of phenol in the presence of oxone. It is concluded that Mn3O4/p(DCPD)HIPE nanocomposite is a highly active catalyst to generate sulfate radicals for phenol degradation Complete removal of 25 mg/L phenol was achieved in 30 min under the conditions of [catalyst] = 0.8 g/L, [oxone] = 2 g/L, and T = 25°C. The phenol degradation followed the pseudo-first-order kinetic model, and the highest kinetic constant of 0.0611 min-1 was achieved. No significant loss in the activity of the catalyst was determined after four consecutive cycles. The results came from multiple reactions, including the reaction of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9Category: chlorides-buliding-blocks)
