Arene-ruthenium(II) and bis(allyl)-ruthenium(IV) complexes containing 2-(diphenylphosphanyl)pyridine ligands: Potential catalysts for nitrile hydration reactions?

Neutral arene-ruthenium(II) complexes [RuCl2(eta6- arene){kappa1-(P)-PPh2py}] and [RuCl2(eta 6-arene){kappa1-(P)-PPh2(py-4-NMe 2)}] (arene = benzene, p-cymene, mesitylene, hexamethylbenzene) have been synthesized and studied as potential catalysts for the selective hydration of nitriles to amides using benzonitrile as a model substrate. The effectiveness of these complexes was low due to the high tendency of the 2- (diphenylphosphanyl)pyridine ligands to form stable kappa2-(P,N)- chelate rings, as demonstrated by NMR spectroscopy and catalytic experiments performed with the isolated cationic derivatives [RuCl(eta6-arene) {kappa2-(P,N)-P N}][SbF6] [P N = PPh2py, PPh2(py-4-NMe2)]. Despite its reluctance to adopt a chelating kappa2-(P,N) coordination mode, cooperative effects of the bulky 2-(diphenylphosphanyl)pyridine ligand PPh2(py-6-tert-amyl) were not observed in complexes [RuCl2(eta6-arene) {kappa1-(P)-PPh2(py-6-tert-amyl)}] (arene = benzene, p-cymene). The novel bis(allyl)-ruthenium(IV) derivatives [RuCl(eta 3:eta3-C10H16) {kappa2-(P,N)-P N}][SbF6] [P N = PPh2py, PPh2(py-4-NMe2)] and [RuCl2(eta3: eta3-C10H16){kappa1-(P)-PPh 2(py-6-tert-amyl)}] (C10H16 = 2,7-dimethylocta-2,6-diene-1,8-diyl) were also synthesized and fully characterized, and again led to modest conversions in the benzonitrile hydration reaction. Improvements in the catalytic activities of complexes [RuCl 2(eta6-p-cymene){kappa1-(P)-PPh 2py}], [RuCl(eta6-p-cymene){kappa2-(P,N)- PPh2py}][SbF6] and [RuCl(eta3: eta3-C10H16){kappa2-(P,N)- PPh2py}][SbF6] were observed in the presence of excess PPh2py due to the in situ formation of the catalytically more active dication [Ru{kappa2-(P,N)-PPh2py}3] 2+.

Ruthenium-catalyzed oxidative cyanation of tertiary amines with molecular oxygen or hydrogen peroxide and sodium cyanide: Sp3 C-H bond activation and carbon-carbon bond formation

Ruthenium-catalyzed oxidative cyanation of tertiary amines with molecular oxygen in the presence of sodium cyanide and acetic acid gives the corresponding alpha-aminonitriles, which are highly useful intermediates for organic synthesis. The reaction is the first demonstration of direct sp3 C-H bond activation alpha to nitrogen followed by carbon-carbon bond formation under aerobic oxidation conditions. The catalytic oxidation seems to proceed by (i) alpha-C-H activation of tertiary amines by the ruthenium catalyst to give an iminium ion/ruthenium hydride intermediate, (ii) reaction with molecular oxygen to give an iminium ion/ruthenium hydroperoxide, (iii) reaction with HCN to give the alpha-aminonitrile product, H2O2, and Ru species, (iv) generation of oxoruthenium species from the reaction of Ru species with H2O2, and (v) reaction of oxoruthenium species with tertiary amines to give alpha-aminonitriles. On the basis of the last two pathways, a new type of ruthenium-catalyzed oxidative cyanation of tertiary amines with H2O2 to give alpha-aminonitriles was established. The alpha-aminonitriles thus obtained can be readily converted to alpha-amino acids, diamines, and various nitrogen-containing heterocyclic compounds.

New organoruthenium compounds with pyrido[2?,3?:5,6]pyrazino[2,3-f][1, 10]phenanthroline: synthesis, characterization, cytotoxicity, and investigation of mechanism of action

Abstract: Three new ruthenium(II)-arene complexes with pyrido[2?,3?:5,6]pyrazino[2,3-f][1, 10]phenanthroline (ppf) of general formula: C1 ([(?6-benzene)Ru(ppf)Cl]PF6, C2 ([(?6-toluene)Ru(ppf)Cl]PF6) and C3 ([(?6-p-cymene)Ru(ppf)Cl]PF6) have been synthesized. The structures of complexes were determined by elemental analysis, IR, ESI?MS, as well as with 1H and 13C NMR spectroscopy. Cytotoxic activity has been evaluated in three different human neoplastic cell lines (A549, A375, LS 174T) and in one human non-tumor cell line (MRC-5), by the MTT assay. Complexes C1?C3 showed IC50 values in the micromolar range below 100?muM. Complex C3, carrying ?6-p-cymene as the arene ligand, exhibited cytoselective activity toward human malignant melanoma A375 cells (IC50 = 15.8 ¡À 2.7?muM), and has been selected for further analyses of its biological effects. Drug-accumulation study performed in the A375 cells disclosed that C3 possess lower ability of entering the cells compared to cisplatin and distributes approximately equally in the cytosol and membrane/organelle fraction of cells. Investigations in the 3D model of A375 cells, disclosed different effects of the complex C3 and cisplatin on growth of multicellular tumor spheroids (MCTSs). While the size of cisplatin-treated MCTSs decreased with time, MCTSs treated with C3 continued to growth. Differences in structural organization and biological activity of this type of ruthenium(II)-arene complexes versus cisplatin in A375 malignant melanoma cells pointed out their different modes of action, and necessity for further biological studies and optimizations for potential applications.

Synthesis and Structures of Arene Ruthenium (II)?NHC Complexes: Efficient Catalytic alpha-alkylation of ketones via Hydrogen Auto Transfer Reaction

A panel of six new arene Ru (II)-NHC complexes 2a-f, (NHC?=?1,3-diethyl-(5,6-dimethyl)benzimidazolin-2-ylidene 1a, 1,3-dicyclohexylmethyl-(5,6-dimethyl)benzimidazolin-2-ylidene 1b and 1,3-dibenzyl-(5,6-dimethyl)benzimidazolin-2-ylidene 1c) were synthesized from the transmetallation reaction of Ag-NHC with [(eta6-arene)RuCl2]2 and characterized. The ruthenium (II)-NHC complexes 2a-f were developed as effective catalysts for alpha-alkylation of ketones and synthesis of bioactive quinoline using primary/amino alcohols as coupling partners respectively. The reactions were performed with 0.5?mol% catalyst load in 8?h under aerobic condition and the maximum yield was up to 96%. Besides, the different alkyl wingtips on NHC and arene moieties were studied to differentiate the catalytic robustness of the complexes in the transformations.
