Reactivity studies of cyclopentadienyl ruthenium(II), osmium(II) and pentamethylcyclopentadienyl iridium(III) complexes towards 2-(2?-pyridyl)imidazole derivatives

The reaction of [CpRu(PPh3)2Cl] and [CpOs(PPh3)2Br] with chelating 2-(2?-pyridyl)imidazole (N ? N) ligands and NH4PF6 yields cationic complexes of the type [CpM(N ? N)(PPh3)]+ (1: M = Ru, N ? N = 2-(2?-pyridyl)imidazole; 2: M = Ru, N ? N = 2-(2?-pyridyl)benzimidazole; 3: M = Ru, N ? N = 2-(2?-pyridyl)-4,5-dimethylimidazole; 4: M = Ru, N ? N = 2-(2?-pyridyl)-4,5-diphenylimidazole; 5: M = Os, N ? N = 2-(2?-pyridyl)imidazole; 6: M = Os, N ? N = 2-(2?-pyridyl)benzimidazole). They have been isolated and characterized as their hexafluorophosphate salts. Similarly, in the presence of NH4PF6, [Cp*Ir(mu-Cl)Cl]2 reacts in dry methanol with N ? N chelating ligands to afford in excellent yield [Cp*Ir(N ? N)Cl]PF6 (7: N ? N = 2-(2?-pyridyl)imidazole; 8: N ? N = 2-(2?-pyridyl)benzimidazole). All the compounds have been characterized by infrared and NMR spectroscopy and the molecular structure of [1]PF6, [2]PF6 and [7]PF6 by single-crystal X-ray structure analysis.

Poly(alkylidenamines) dendrimers as scaffolds for the preparation of low-generation ruthenium based metallodendrimers

The aim of this article is to highlight the use of nitrile-functionalized poly(alkylidenamines) dendrimers as building blocks for the preparation of low-generation ruthenium based cationic metallodendrimers having in view potential biomedical applications. Air-stable poly(alkylidenamines) nitrile dendrimers, peripherally functionalized with the ruthenium moieties [Ru(eta5-C5H5)(PPh3) 2]+ or [RuCl(dppe)2]+, have been prepared, characterized and are being studied for their anticancer activity. The followed strategy is based on the biological advantages associated with low-generation dendrimers, the known activity of ruthenium compounds as anticancer drugs and the stability of these dendrimers at the physiological temperature.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.SDS of cas: 32993-05-8, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 32993-05-8, in my other articles.

Half-sandwich cyclopentadienyl ruthenium complexes of achiral and chiral diphosphazanes

Reaction of [CpRu(PPh3)2Cl] (1) {Cp = eta5-(C5H5)} with X2PN(CHMe2)PYY? {X = Y = Y? = Ph (L1); X = Y = Ph, Y? = OC6H4Me-4 (L4); X = Y = Ph, Y? = OC6H3Me2-3,5 (L5); X = Y = Ph, Y? = N2C3HMe2 (L6)} yields the cationic chelate complexes, [CpRu(eta2-(X2PN(CHMe2)PYY?))PPh3 ]Cl. On the other hand, the reaction of 1 with X2PN(CHMe2)-PYY? {X2 = YY? = O2C6H4(L2)} gives the complex, [CpRu(eta1-L2)2PPh3]Cl. Both types of complexes are formed with X2PN(CHMe2)PYY? {X = Ph, YY? = O2C6H4 (L3)}. The reaction of 1 with (R),(S)-(H12C20O2)PN(CHMe2)PPh2 (L7) yields both cationic and neutral complexes, [CpRu{eta2-(L7)}PPh3]Cl and [CpRu{eta1-(L7)}2PPh3]Cl and [CpRu{eta2-(L7)}-Cl]. The reactions of optically pure diphosphazane, Ph2PN(*CHMePh)PPhY (Y = Ph (L8); Y = N2C3HMe2-3,5 (L9)) with 1 give the neutral and cationic ruthenium complexes, [CpRu{eta2-(Ph2PN(R)PPhY)}Cl] and [CpRu{eta2-(ph2PN(R)-PPhY)}PPh3]Cl. “Chiral-at-metal” ruthenium complexes of diphosphazanes have been synthesized with high diastereo-selectivity. The absolute configuration of a novel ruthenium complex, (SCSPRRu)-[(eta5-C5H 5)Ru* {eta2-(Ph2PN(*CHMePh)-P*Ph(N2C 3HMe2-3,5))}Cl] possessing three chiral centers, is established by X-ray crystallography. The reactions of [CpRu{eta2-(L8)}Cl] with mono or diphosphanes in the presence of NH4PF6 yield the cationic complexes, [CpRu{eta2-(L8)}{eta1-(P)}]PF6 {P = P(OMe)3, PPh3, Ph2P(CH2)nPPh2 (n = 1 or 2)}.

Syntheses, characterization and structure determination of {[CpRu(X)]2(eta2,mu2-dppe)2} complexes (X=Cl, N3; Dppe=Ph2PCH2CH2PPh2): Chelating vs. bridging behavior of a classical bidentate ligand

Phosphine substitution reactions between (eta5-C5H5)Ru(PPh3)2Cl (1) and 1,2-bis(diphenylphosphino)ethane (Ph2P(CH2)2PPh2, dppe), in refluxing benzene or in toluene at 80C afforded a mixture of complexes where dppe behaves both as a bridging and as a chelating ligand. CpRu(eta2-dppe)Cl (2) and {[CpRu(Cl)]2(eta2,mu2-dppe)2} (3) were separated by fractional precipitation from the reaction mother-liquor, and were characterized by 1H, 13C, 31P NMR, elemental analysis and IR spectroscopy. The (2):(3) ratio in the composition of the reaction product was found to be independent of the reaction time. In solution and at room temperature, (3) exists in both boat and chair conformers of a 10-membered ring, while at lower temperatures, and in the solid-state, only the chair conformer is observed. Compounds (2) and (3) undergo halide-displacement upon reacting with NaN3 in the presence of ethanol to yield CpRu(eta2-dppe)(N3) (4) and {[CpRu(N3)]2(eta2,mu2-dppe) 2} (5), respectively. The crystal structures of (3) and (5) were determined. Elsevier Science Ltd.

Cyclopentadienyl RuII Complexes as Highly Efficient Catalysts for the N-Methylation of Alkylamines by Methanol

The ruthenium(II) half-sandwich complex [RuCl(eta5-C5H5)(PPh3)2] (1) catalyses the reaction between methanol and alkylamines RNH2 or R1R2NH to afford RN(CH3)2 and R1R2NCH3 products, respectively. The reaction is quantitative and generally fast, at the methanol reflux temperature, for a wide spectrum of substrates. Starting form primary amines, the stepwise formation of RN=CH2, RNHCH3, and RN(CH3)2 has been observed. Both PPh3 and Cl- dissociation from 1 are key-steps in forming the effective catalytic species. The catalytic activity of several half-sandwich neutral or cationic complexes (2-15) related to 1 is also discussed.

New bis(phosphines) derived from N,N?-substituted ethylenediamine derivatives. Synthesis and transition metal chemistry of X2PN(R)CH2CH2(R)NPX2 (R = CH2Ph or Ph, X = Ph; R = CH2Ph, X2 = O2C6H4).

The bis(phosphines) of the type X2PN(R)CH2CH2(R)NPX2 (R = Ph or CH2Ph, X = Ph; R = CH2Ph, X2 = O2C6H4) with the ethylenediamine framework were prepared by reaction of X2PCl with the corresponding N,N?-substituted ethylenediamine derivatives. These ligands readily formed complexes with Group 6 metals and RuII, NiII, PdII and PtII. All complexes were characterised by elemental analysis, IR and NMR spectroscopic methods of which 31P-{1H} is most valuable. The structures of the bis(phosphine) ligand Ph2PN(CH2Ph)CH2CH2(CH 2Ph)NPPh2 and its platinum(II) complex cis-[PtCl2{PPh2N(CH2Ph)CH2CH 2(CH2Ph)NPPh2}] were determined by X-ray crystallography. The ligand crystallises in the extended conformation with both the nitrogen atoms nearly planar and the bond angles around them close to 120. The P-N distances are shorter than normally accepted P-N single bond lengths (ca. 1.77 A) suggesting some degree of P-N pi bonding. The seven-membered chelate ring in the platinum complex is non-planar but the metal atom is in a typical square planar environment with two phosphorus atoms and two chlorine atoms in a mutually cis disposition and the ethylenediamine bridge is folded with respect to the plane in an “open envelope” fashion.

Syntheses and molecular structures of group 8 benzonitrile complexes

The molecular structures of eight nitrile complexes of general form [M(NCC6H4R-4)(L2)Cp?]PF6 [M = Fe, Ru; L2 = dppe, (PPh3)2; Cp? = Cp, Cp*] are reported and discussed in terms of the nature of the M-N interaction. Data are consistent with a predominantly sigma-interaction, similar to that found in related acetylide complexes, with little evidence for metal to nitrile pi-back bonding interactions.
