《Degradable Polyphosphoramidate via Ring-Opening Metathesis Polymerization》 was published in ACS Macro Letters in 2020. These research results belong to Liang, Yifei; Sun, Hao; Cao, Wei; Thompson, Matthew P.; Gianneschi, Nathan C.. Formula: C43H72Cl2P2Ru The article mentions the following:

We report the synthesis of a degradable polyphosphoramidate via ring-opening metathesis polymerization (ROMP) with the Grubbs initiator (IMesH2)(C5H5N)2(Cl)2Ru = CHPh. Controlled ROMP of a low ring strain diazaphosphepine based cyclic olefin was achieved at low temperatures to afford well-defined polymers that readily undergo degradation in acidic conditions via the cleavage of the acid-labile phosphoramidate linkages. The diazaphosphepine monomer was compatible in random and block copolymerizations with Ph and oligo(ethylene glycol) bearing norbornenes. This approach introduced partial or complete degradability into the polymer backbones. With this chem., we accessed amphiphilic poly(diazaphosphepine-norbornene) copolymers which could be used to prepare micellar nanoparticles. In the experiment, the researchers used Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9Formula: C43H72Cl2P2Ru)

A method was described to generate alkylidene carbenes via tetramethylammonium-fluoride-induced desilylation of silyl vinyl iodides. The reversible carbene generation from an iodovinyl anion enabled us to unearth mechanistic aspects of the trimethylenemethane (TMM) diyl cyclization reaction that could not be explored via previous methods. A slow diyl-diylophile cycloaddition could induce the reversible formation of an alkylidene carbene from the TMM diyl intermediate via a retro-cyclopropanation at ambient temperature was also observed The experimental part of the paper was very detailed, including the reaction process of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9Related Products of 172222-30-9)

《Robust Olefin Metathesis Catalyst Bearing a Tridentate Hemilabile NHC Ligand》 was published in Organometallics in 2020. These research results belong to Yoon, Joseph S.; Cena, Nicolas; Schrodi, Yann. HPLC of Formula: 172222-30-9 The article mentions the following:

An olefin metathesis catalyst bearing a tridentate hemilabile N-heterocyclic carbene (NHC) ligand was synthesized and characterized. The solid-state crystal structure reveals coordination from all three donation sites of the NHC ligand, giving rise to a stable 18-electron complex. Catalytic activity in three standard metathesis reactions was demonstrated, revealing the authors’ catalyst to be particularly long lived and highly selective in the self-metathesis of 1-decene. Although the catalyst in this work initiates more slowly than its 2nd-generation counterparts, it has high thermal stability, yielding peak performances at higher temperatures The unique ligand framework of this catalyst may serve as a template for the synthesis of analogous catalysts with improved efficiencies.

Recommanded Product: 172222-30-9In 2022 ,《Tuning Single-Polymer Growth via Hydrogen Bonding in Conformational Entanglements》 appeared in ACS Central Science. The author of the article were Baral, Susil; Liu, Chunming; Mao, Xianwen; Coates, Geoffrey W.; Chen, Peng. The article conveys some information:

Synthetic polymers have widespread applications in daily life and advanced materials applications. Making polymers efficiently and controllably is highly desired, for which modulating intramol. and intermol. interactions have been an effective approach. Recent real-time single-polymer growth studies uncovered nonequilibrium conformational entanglements that form stochastically under living polymerization conditions and which appear to plausibly play key roles in controlling the polymerization kinetics and dispersion. Here, using magnetic tweezers measurements, we study the real-time polymerization dynamics of single polynorbornene-based polymers in which we systematically tune the hydrogen-bonding interactions by titrating the OH content in the monomers and the formed polymers during ring opening metathesis polymerization Using norbornenes with and without a hydroxyl group and a nonreactive monomer analog, we show that intrachain and intermol. hydrogen bonding compete, and both alter the microscopic properties of the nonequilibrium entanglements, leading to surprising multiphasic dependences of polymerization dynamics on the polymer’s OH content. We further formulate a simple model to rationalize quant. the observed multiphasic behaviors by considering the different scaling relations of intrachain and intermol. hydrogen bonding on the OH content. These results provide insights into the interconnected roles of intra-/intermol. interactions, polymer chain conformations, and free monomers in solution in affecting polymerization kinetics and dispersion, and point to new opportunities in manipulating polymerization reactions.

《A Furan-2,5-diyl Bridged Macrocage as a Highly Distorted Molecular Gyrotop》 was published in Chemistry Letters in 2020. These research results belong to Inagaki, Yusuke; Ueda, Satsuki; Yamaguchi, Kentaro; Setaka, Wataru. Reference of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium The article mentions the following:

A novel mol. gyrotop with a furan-2,5-diyl was synthesized. The furan-diyl rotor showed rotation inside the cage in a solution However, no furan-rotor dynamics was observed in a crystalline state, while a corresponding thiophene-diyl derivative showed rotation in the same condition. The lack of dynamics in the furan derivative resulted from the deformed structure of the cage caused by the small intersecting angle between two Si-C(aromatic) bonds.

Yasir, Mohammad; Kilbinger, Andreas F. M. published their research in ACS Macro Letters in 2021. The article was titled 《Cascade Ring-Opening/Ring-Closing Metathesis Polymerization of a Monomer Containing a Norbornene and a Cyclohexene Ring》.Recommanded Product: 172222-30-9 The article contains the following contents:

Norbornene is polymerized extremely fast when reacted with Grubbs’ first (G1) or third generation catalyst (G3) because of its very high ring strain energy. Cyclohexene, on the other hand, cannot be polymerized using G1 or G3 due to its very low ring strain energy. Subsequently, the sequence-selective polymerization of these two monomers is extremely challenging. A sequence-selective cascade ring-opening/ring-closing metathesis polymerization of the monomer M containing both the norbornene and the cyclohexene ring using G1 or G3 is reported. The polymer structure was analyzed by 1H NMR, 1H-1H COSY, and 1H-1H ROESY spectroscopy and MALDI-ToF mass spectrometry. Polymers with moderate mol. weight dispersities and good mol. weight control were achieved by varying the ratio between monomer M and G1.Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9Recommanded Product: 172222-30-9) was used in this study.

In 2022,Yasir, Mohammad; Singh, Manvendra; Kilbinger, Andreas F. M. published an article in ACS Macro Letters. The title of the article was 《A Single Functionalization Agent for Heterotelechelic ROMP Polymers》.Reference of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium The author mentioned the following in the article:

Heterotelechelic polymers are an important class of materials finding applications in bioconjugation, imaging, sensing, and synthesis of organic/inorganic hybrid systems with interesting features. However, the synthesis of such polymers is challenging. Here, we report a mechanistically unique and most efficient method based on a single functionalization agent to prepare heterotelechelic polymers by a ring-opening metathesis polymerization Different functionalization agents can be synthesized in one simple step from inexpensive com. starting materials. The functionalization agents initially generate a functional initiator from com. Grubbs’ first-generation ruthenium benzylidene catalyst. During this process, a functional dihydrofuran derivative is produced. After functional initiation and propagation of a suitable monomer, the dihydrofuran derivative functionally terminates the polymerization yielding a primary alc.-terminated heterotelechelic polymer. Mol. weight control is achieved by varying the ratio between monomer and Grubbs’ first-generation catalyst. This method may emerge as a popular choice to prepare heterotelechelic polymers due to its simplicity and efficiency.

In 2022,Kim, Jong-Hyun; Kwon, Dong-Jun; DeVries, K. Lawrence; Park, Joung-Man published an article in Fibers and Polymers. The title of the article was 《Innovative Ru Catalyst Adopting for Improving Interfacial and Mechanical Properties on CF Fabric Reinforced ENB Composites》.COA of Formula: C43H72Cl2P2Ru The author mentioned the following in the article:

This study improved the interfacial and mech. properties of carbon fiber (CF) reinforced 5-ethylidene-2-norbornene (ENB) composites using the Ru catalyst coating method on CF for vacuum-assisted resin transfer molding (VARTM). Generally, the Ru catalyst added ENB was polymerized using mixing two materials. The interfacial and mech. properties of the composites containing Ru catalyst coated carbon fabric were higher than those in which Ru catalyst was mixed in the ENB before being embedded in the CF fabric. It can be mainly due to the uniform or random dispersion of Ru catalyst by two different manufacturing processes. The interfacial properties determined using the microdroplet test, e.g., the surface energy and work of adhesion, Wa, were consistent with macro-mech. properties. From the T-peel test combined with elec. resistance (ER), the Ru catalyst coated CF fabric/ENB composite responded reasonably well with high peeling strength. The different Ru catalyst processing methods resulted in different interfacial, mech., and elec. sensing properties, with the Ru catalyst coated CF composites typically having better properties. This study is about the Ru catalyst coated CF fabric, which can be applied to manufacture geometrically complex and large structural composites and will help improve product manufacturing efficiency and quality.

《Synthesis and rhodium complexes of macrocyclic PNP and PONOP pincer ligands》 was written by Hood, Thomas M.; Gyton, Matthew R.; Chaplin, Adrian B.. Reference of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium And the article was included in Dalton Transactions in 2020. The article conveys some information:

The synthesis of macrocyclic variants of commonly employed phosphine-based pincer ligands derived from lutidine (PNP-14) and 2,6-dihydroxypyridine (PONOP-14) is described, where the P-donors are trans-substituted with a tetradecamethylene linker. This was accomplished using an eight-step procedure involving borane protection, ring-closing olefin metathesis, chromatog. separation from the cis-substituted diastereomers, and borane deprotection. The rhodium coordination chem. of these ligands has been explored, aided by the facile synthesis of 2,2′-biphenyl (biph) adducts [Rh(PNP-14)(biph)][BArF4] and [Rh(PONOP-14)(biph)][BArF4] (ArF = 3,5-(CF3)2C6H3). Subsequent hydrogenolysis enabled generation of dihydrogen, ethylene and carbonyl derivatives; notably the ν(CO) bands of the carbonyl complexes provide a means to compare the donor properties of the new pincer ligands with established acyclic congeners.
