Pentamethylcyclopentadienyl ruthenium(II) complexes of para-substituted N-(pyrid-2-ylmethylene)-phenylamine ligands: Syntheses, spectral and structural studies

The reaction of [(eta5-C5Me5)Ru(PPh 3)2Cl] (1) with acetonitrile in the presence of excess NH4PF6 leads to the formation of the cationic ruthenium(II) complex [(eta5-C5Me5) Ru(PPh3)2(CH3CN)]PF6 (2). The complex (2) reacts with a series of N,N? donor Schiff base ligands viz. para-substituted N-(pyrid-2-ylmethylene)-phenylamines (ppa) in methanol to yield pentamethylcylopentadienyl ruthenium(II) Schiff base complexes of the formulation [(eta5-C5Me5)Ru(PPh 3)(C5H4N-2-CHN-C6H 4-p-X)]PF6 [3a]PF6-[3f]PF6, where C5Me5 = pentamethylcylopentadienyl, X = H, [3a]PF 6, Me, [3b]PF6, OMe, [3c]PF6, NO2, [3d]PF6, Cl, [3e]PF6, COOH, [3f]PF6. The complexes were isolated as their hexafluorophosphate salts. The complexes were fully characterized on the basis of elemental analyses and NMR spectroscopy. The molecular structure of a representative complex, [(eta5-C 5Me5)Ru(PPh3)(C5H 4N-2-CHN-C6H4-p-Cl)]PF6 [3e]PF 6, has been established by X-ray crystallography.

A comparison of Cp*- and Tp-ruthenium carbyne complexes prepared via site selective electrophilic addition to neutral ruthenium vinylidenes

The synthesis and characterization of a series of ruthenium carbyne complexes supported by either pentamethylcyclopentadienyl (Cp*) or hydridotris(pyrazolyl)borate (Tp) ligands are discussed. Reacting the neutral ruthenium(II) vinylidenes [Cp*Cl(PPh3)Ru(CCHR)] (1) or [TpCl(PPh3)Ru(CCHR)] (2) with excess HBF4 ? Et 2O yields the ruthenium(IV) carbynes [Cp*Cl(PPh 3)Ru(CCH2R)][BF4] (3: R = tBu, 3a; R = nBu, 3b; R = Ph, 3c), and [TpCl(PPh3)Ru(CCH 2R)][BF4] (4: R = tBu, 4a; R = nBu, 4b; R = Ph, 4c). Complexes 3a and 3b are isolable solids, whereas 3c and 4a-c must be prepared and examined in solution at low temperatures using variable temperature NMR spectroscopy. In contrast, reactions of 1 or 2 (R = Ph) with MeOTf selectively yield the chloride abstracted products [Cp*(OTf) (PPh3)Ru(CCHPh)] (5) or [Tp(OTf)(PPh3)Ru(CCHPh)] (6), respectively, along with one equivalent of MeCl. When R = tBu or nBu, the reactions are much less selective. The relative stabilities of the complexes reported are compared and discussed.

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 92361-49-4 is helpful to your research., Synthetic Route of 92361-49-4

Pyramidal stability of 16-electron half-sandwich intermediates [CpRu(P-P)]+ with P-P ligands forming four- to six-membered chelate rings

This paper reports the synthesis, isomer separation, and X-ray characterization of the compounds (SRu,Sc)-/(RRU,Sc)- [CpRu(Chairphos)Cl], Chairphos = (S)-1,3-bis(diphenylphosphanyl)butane, and cis-/trans-[CpRu(Dppm-Me)Cl], Dppm-Me = 1,1-bis(diphenylphosphanyl)etnane. The Cl/I exchange reactions proceeded with predominant retention of the metal configuration, accompanied by some inversion, except for rrai-[CpRu(Dppm- Me)Cl], which was stereospecifically converted to trans-[CpRu(Dppm-Me)I]. Temperature-dependent kinetic measurements afforded rates and activation parameters of the Cl/I exchange and epimerization reactions that follow basilica-type energy profiles. Dissociation of CF from [CpRu(Chairphos)Cl] and [CpRu(Dppm-Me)Cl] gives pyramidal intermediates [CpRu(Chairphos)]+ and [CpRu(Dppm-Me)]+, which maintain the metal configuration. The 16-electron intermediates can react with excess I- to form the iodo complexes with retention of the metal configuration, or they can change the metal configuration by pyramidal inversion, leading to formation of iodo complexes with inverted metal configuration. The kinetic measurements show that the pyramidal inversion via planar transition states depends on the P-Ru-P’ angles. It increases with decreasing chelate ring size, because small P-Ru-P’ angles resist planarization in the transition, which requires larger P-Ru-P’ angles.

Click chemistry approach for the regioselective synthesis of iso-indoline-1,3-dione-linked 1,4 and 1,5 coumarinyl 1,2,3-triazoles and their photophysical properties

Copper-catalyzed reaction of N-propargyl isoindoline-1,3-dione and 4-azidomethyl coumarins / 4-azidomethyl-1-aza coumarins under click chemistry conditions afforded 1,4-disubstituted 1,2,3-triazoles, whereas ruthenium catalysis yielded isomeric 1,5-disubstituted 1,2,3-triazoles. The two regioisomers have been distinguished by NOE studies. UV absorption for a given pair of isomers exhibited similar trend, whereas fluorescence measurements showed considerable differences. Photo physical studies on the interaction of azides with copper and ruthenium have also been performed.

Selective linear coupling reaction of acetylene and acrylonitrile catalyzed by the well-defined metallacyclopentadiene complex C5Me5(PPh3)(Cl)RuCH=CHCH=CH

The metallacyclopentadiene complex C5Me5(PPh3)(Cl)RuCH=CHCH=CH (1) was found to catalyze the linear coupling reaction of acetylene and acrylonitrile to give predominantly 2(E),4(Z),6-heptatrienenitrile (3; TON = 15, 85% selectivity). The coupling reaction is proposed to occur via an initial PPh3 dissociation from 1 and the subsequent insertion of acrylonitrile.

Conversion of Coordinated Carbon Monoxide into Carbon Dioxide via Oxygen-atom transfer from Coordinated Nitrite: Thermolysis of Ru(NO2)2(CO)2(PPh3)2

The thermolysis (111 deg C, toluene solution) of Ru(NO2)2(CO)2(PPh3)2 in the presence of excess PPh3 procced according to the stoichiometry Ru(NO2)2(CO)2(PPh3)2 + PPh3 -> Ru(NO2)2(PPh3)2 + CO2 + CO + Ph3PO.Two highly selective oxygen-atom transfer processes are involved in the overall thermolysis reaction: (i) Ru(NO2)2(CO)2(PPh3)2 -> Ru(ONO)(CO)(NO)(PPh3)2 + CO2; (ii) Ru(ONO)(CO)(NO)(PPh3)2 + PPh3 -> Ru(NO2)2(PPh3)2 + CO + Ph3PO.The intermediate complex Ru(ONO)(CO)(NO)(PPh3)2 was synthesized independently and has been characterized by analytical and spectral methods.The thermolysis of Ru(N18O2)2(CO)2(PPh3)2 unambiguosly establishes coordinated NO2- as the source of oxygen in the conversion of coordinated CO into CO2.Moreover, the extent of 18O enrichment in the CO2 product indicates that statistical scrambling of oxygen occurs between nitrogen and carbon atoms prior to the loss of CO2.The results of a double-label study involving the thermolysis of Ru(N18O2)2(CO)2(PPh3)2 and Ru(NO2)2(13CO2)2 are consistent with an intermolecular mechanism for oxygen-atom transfer from NO2- to CO.Additional mechanistic implications are described.

Poly(alkylidenimine) dendrimers functionalized with the organometallicmoiety [Ru(nu 5-C5H5)(PPh3)2]+ as promising drugs against cisplatin-resistant cancer cells and humanmesenchymal stem cells

Here and for the first time, we show that the organometallic compound [Ru(nu5-C5H5)(PPh3)2Cl] (RuCp) has potential to be used as a metallodrug in anticancer therapy, and further present a new approach for the cellular delivery of the [Ru(nu5-C5H5)(PPh3)2]+ fragment via coordination on the periphery of low-generation poly(alkylidenimine) dendrimers through nitrile terminal groups. Importantly, both the RuCp and the dendrimers functionalized with [Ru(nu5-C5H5)(PPh3)2]+ fragments present remarkable toxicity towards a wide set of cancer cells (Caco-2, MCF-7, CAL-72, and A2780 cells), including cisplatin-resistant human ovarian carcinoma cell lines (A2780cisR cells). Also, RuCp and the prepared metallodendrimers are active against human mesenchymal stem cells (hMSCs), which are often found in the tumor microenvironment where they seem to play a role in tumor progression and drug resistance.
