Synthetic routes were developed to attach three redox-active metal fragments to cross-conjugated 3-methylidenepentadiyne covalently expanded by diazafluorenylidene: The two alkyne termini of this new ligand were end-capped via a phenylene spacer with ethynyl ferrocene, and a [Ru(bpy)2]2+ fragment was coordinated in the diimine binding site. The photophysical and electrochemical properties of both the diferrocenyl-terminated ligand and its corresponding Ru-complex were investigated by UV-vis absorption spectroscopy and cyclic voltammetry. The absorption data reveal significant interactions of the metal centers with the cross-conjugated ligand system. In the electrochemical experiments the ferrocenyl and the ruthenium centers could be addressed individually as they are separated by almost 1 V. While the presence of the Ru-fragment manifests itself in the reduction potential of the diazafluorenylidene-ligand, communication between the ferrocenyl end-caps on one hand and between the ferrocenes and the Ru-fragment on the other appears to be reduced through the freely rotating phenylene spacers.

We describe structure-based design and chemical synthesis of a simplified analog of bistramide A, which potently and reversibly binds monomeric actin with a Kd of 9.0 nM, depolymerizes filamentous actin in vitro and in A549 (nonsmall cell lung cancer) cells, inhibits growth of cancer cell lines in vitro at submicromolar concentrations, and significantly suppresses proliferation of A549 cells in a nude mice tumor xenograft model in terms of both tumor growth delay and average tumor volume. This study provides a conceptual framework for the design and development of new antiproliferative compounds that target cytoskeletal organization of cancer cells in vivo by a combination of reversible G-actin binding and effective F-actin severing.

Reference of 301224-40-8, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.301224-40-8, Name is (1,3-Dimesitylimidazolidin-2-ylidene)(2-isopropoxybenzylidene)ruthenium(VI) chloride, molecular formula is C31H38Cl2N2ORu.

The reaction of SnCl2 with the Ru-Cl bond of the Grubbs I catalyst RuCl2(=CHPh)(PCy3)2 (1) gives the complex {[Ru(=CHPh)(SnCl3)(PCy3)]2(mu-Cl) 3}-[HPCy3]+ (2), but containing two diethyl ether solvate molecules. The formal insertion of SnCl2 into one Ru-Cl bond of the Hoveyda II catalyst RuCl2(=CH-C 6H4OPri)(H2IMes) (3) (H 2IMes = N,N?-dimesityl-4,5-dihydroimidazol-2-ylidene) results in formation of the new complex RuCl(SnCl3)(=CH-C6H 4OPri)(H2IMes) (4). The X-ray analyses of 2 and 4 show the presence of very short Ru-Sn bonds (2.5834(9) A mean bond for 2 and 2.5925(12) A for 4) and the retention of short Ru=C bonds (1.895(10) and 1.825(8) A, respectively). Complex 4 shows an excellent catalytic activity for the cross-metathesis of plant oil derivatives, the C11 omega-unsaturated ester and aldehyde and the unsaturated C18 diester with acrylonitrile, and a good activity for their cross-metathesis with methyl acrylate. Good to excellent yield of alpha,omega-bifunctional compounds, precursors of polyesters and polyamides, were obtained. Complex 2 shows catalytic activity for the self-metathesis of C11 omega-unsaturated aldehyde at low concentration to produce C20 alpha,omega-dialdehyde.

Migrastatin and isomigrastatin analogues have been synthesised in order to contribute to structure-activity studies on tumour cell migration inhibitors. These include macrocycles varying in ring size, functionality and alkene stereochemistry, as well as glucuronides. The synthesis work included application of the Saegusa-Ito reaction for regio- and stereoselective unsaturated macroketone formation, diastereoselective Brown allylation to generate 9-methylmigrastatin analogues and chelation-induced anomerisation to vary glucuronide configuration. Compounds were tested in vitro against both breast and pancreatic cancer cell lines and inhibition of tumour cell migration was observed in both wound-healing (scratch) and Boyden chamber assays. One unsaturated macroketone showed low affinity for a range of secondary drug targets, indicating it is at low risk of displaying adverse side effects.

The modification of methyl ricinoleate by etherification of the hydroxyl group was accomplished by using a nonclassical ruthenium-catalyzed allylation reaction and also by esterification. Methyl ricinoleate derivatives were engaged in ring-closing metathesis (RCM) reactions leading to biosourced 3,6-dihydropyran and alpha,beta-unsaturated lactone derivatives with concomitant production of polymer precursors. Sequential RCM/hydrogenation and RCM/cross-metathesis were also implemented as a straightforward method for the synthesis of tetrahydropyran and lactone derivatives as well as valuable monomers (i.e., polyamide precursors).

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: (1,3-Dimesitylimidazolidin-2-ylidene)(2-isopropoxybenzylidene)ruthenium(VI) chloride, you can also check out more blogs about301224-40-8

A new family of cationic organometallic chloro compounds of the type [(arene)Ru(N,N)(Cl)]+ containing N,N-chelating dipyridylamine ligands has been synthesized and isolated as the chloride salts, which are water soluble and stable to hydrolysis. The resulting mononuclear ruthenium complexes catalyze the transfer hydrogenation of aryl ketones in aqueous solution to give the corresponding alcohols with good conversion and interesting recyclability.

Because of their unique cyclic architectures, tunable electronic properties, and supramolecular chemistries, cycloparaphenylenes (CPPs) have the potential to act as a new class of ligands for coordination cages, metal-organic frameworks, and small-molecule transition-metal complexes. However, currently there is no general strategy to coordinate the cyclic framework to a variety of metal centers. We report here a general and scalable synthetic strategy to embed 2,2?-bipyridine units into the backbone of CPPs. We use this approach to synthesize a 2,2?-bipyridine-embedded [8]CPP, which we show can successfully coordinate to both Pd(II) and Ru(II) metal centers. The resulting coordination complexes, a Pd(II)-nanohoop dimer and a bis(bipyridyl)ruthenium(II)-functionalized nanohoop, show unique solid-state and photophysical properties. This work provides a proof of concept for a general strategy to use nanohoops and their derivatives as a new class of ligands.

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 15746-57-3 is helpful to your research., Synthetic Route of 15746-57-3

This paper describes the successful preparation of new Ru(IV)-pi-allyl complexes having the general formula (C5R5)RuX2(eta3-allyl) (R = H, Me; X = Cl, Br) by the oxidative addition of allylic halides to Ru(II) complexes, (C5R5)Ru(L)2X (R = H, Me; L = CO, PPh3; X = Br, Cl). These new compounds were subjected to NMR analysis to determine the structure, which was confirmed by X-ray crystallographic analysis of a representative compound. During the course of this study, the authors found facile reductive elimination of allylic halides from the Ru(IV)-pi-allyl complexes to form Ru(II)-carbonyl or Ru(II)-arene complexes, induced by contact with CO or aromatic solvents, respectively.
