Water-soluble ruthenium(II) catalysts [RuCl2(eta6- arene)-{P(CH2OH)3}] for isomerization of allylic alcohols and alkyne hydration

The novel water-soluble ruthenium(II) complexes [RuCl 2(eta6-arene){P(CH2OH)3}] 2a-c and [RuCl(eta6-arene){P(CH2OH)3} 2][Cl] 3a-c have been prepared in high yields by reaction of dimers [{Ru(eta6-arene)(mu-Cl)Cl}2] (arene = C 6H6 1a, p-cymene 1b, C6Me6 1c) with two or four equivalents of P(CH2OH)3, respectively. Complexes 2/3a-c are active catalysts in the redox isomerization of several allylic alcohols into the corresponding saturated carbonyl compounds under water/n-heptane biphasic conditions. Among them, the neutral derivatives [RuCl2(eta6-C6H6){P(CH 2OH)3}] 2a and [RuCl2(eta6-p- cymene){P(CH2OH)3}] 2b show the highest activities (TOP values up to 600 h-1; TON values up to 782). Complexes 2/3a-c also catalyze the hydration of terminal alkynes.

The new cationic mononuclear complexes [(eta6-arene)Ru(Ph-BIAN)Cl]BF4 [eta6-arene = benzene (1), p-cymene (2)], [(eta5-C5H5)Ru(Ph-BIAN)PPh3]BF4 (3) and [(eta5-C5Me5)M(Ph-BIAN)Cl]BF4 [M = Rh (4), Ir (5)] incorporating 1,2-bis(phenylimino)acenaphthene (Ph-BIAN) are reported. The complexes have been fully characterized by analytical and spectral (IR, NMR, FAB-MS, electronic and emission) studies. The molecular structure of the representative iridium complex [(eta5-C5Me5)Ir(Ph-BIAN)Cl]BF4 has been determined crystallographically. Complexes 1-5 effectively catalyze the reduction of terephthaldehyde in the presence of HCOOH/CH3COONa in water under aerobic conditions and, among these complexes the rhodium complex [(eta5-C5Me5)Rh(Ph-BIAN)Cl]BF4 (4) displays the most effective catalytic activity.

Highly efficient use of NaOCI in the Ru-catalysed oxidation of aliphatic ethers to esters

The selectivity of alpha-oxidation of ethers to esters via RuNaOCI can be dramatically improved by pH control, at high substrate to catalyst ratios using a stoichiometric amount of hypochlorite in biphasic media at room temperature.

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.Application In Synthesis of Tetrapropylammonium perruthenate, you can also check out more blogs about114615-82-6

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.

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.

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.

A 3-pyridyl-5,15-diazaporphyrin nickel(II) complex as a bidentate metalloligand for transition metals

3-Pyridyl-5,15-diazaporphyrin nickel(II) serves as a bidentate metalloligand for platinum(II), ruthenium(II), and rhenium(I) metal centers. Single-crystal X-ray diffraction analysis of these metal complexes unambiguously reveals the presence of a dative bond between the outer metal center and the meso-nitrogen atom. The UV/Vis absorption spectra of the complexes show substantially red-shifted bands which are perturbed by outer-metal coordination. This is due to the contribution of metal-to-ligand charge transfer interactions.
