Studien zur C-H-Aktivierung IV. Inter- and Intra-molekulare C-H-Aktivierung mit Komplexfragmenten des Typs (M=Ru, Os)

The dihydro ruthenium and osmium complexes C6H6RuH2(PPri3), C6Me6RuH2 (R=Me, Pri) and C6H6OsH2(PPri3) can be obtained from the corresponding dihalogeno derivatives C6R6MX2(L) (X=Cl,I) and NaBH4 or Na.Photolysis, in presence of benzene and toluene, of C6H6RuH2(PPri3) or C6Me6RuH2(PMe3) gives the hydrido(phenyl) and hydrido(tolyl) complexes, C6H6RuH(C6H4R)(PPri3) or C6Me6RuH(C6H4R)(PMe3) (R=H, Me) in 35-63percent yield.C6H6RuH(C6H4Me)(PPri3) or C6Me6RuH(C6H4Me)(PMe3) can also be prepared from C6H6RuBr(C6H4Me)(PPri3) or C6Me6RuBr(C6H4Me)(PMe3) and NaBH4 in ethanol.Photolysis of C6H6RuH2(PPri3 ) in cyclohexane, hexane of mesitylene leads to the formation of the four-membered metallaheterocycle C6H6(H)RuCH2CH(CH3)PPi2<*> which can be isolated as a pair of diastereomers.It reacts smoothly with C6H6, C6D6 and C6H5Me in the dark to give the corresponding aryl(hydrido)ruthenium compounds C6H6RuH(C6H4R)(PPri3) (R=H, Me) and C6H6RuD(C6D5)(PPri3) in almost quantitative yield.In contrast to C6H6RuH2(PPri3), the corresponding osmium complex C6H6OsH2(PPri3) is photochemically inert.C6H6OsH(C6H5)(PPri3), C6H6OsH(C6H5)(PMe3) and C6H6OsD(C6D5)(PMe3) have been obtained from the reaction of C6H6OsI2(PR3) (R=Me, Pri) with NaC10H8 in THF/C6H6 or C6D6, by the classical Chatt route.

A biomimetic model of the electron transfer between P680 and the TyrZ-His190 pair of PSII

Artificial photosynthesis: The first photoelectron trade between P 680 and the TyrZ-His190 pair of Photosystem II was modeled by a ruthenium(II) trisbipyridine type complex that contains a phenol hydrogen atom bonded to an imidazole group. The photogenerated phenoxyl radical has been characterized. This opens up the way for a more complete biomimetic model of Photosystem II.

In Situ routes to catalytically active Ru(0) Species by reduction of readily available, air-stable precursors

Cross-dimerization of a conjugated diene with a substituted alkene catalyzed by in situ reduction of an air-stable Ru(II) catalyst precursor has been achieved. Reaction of 2,3-dimethylbutadiene with styrene is catalyzed by [Ru(acac)2(eta4-1,5-COD)] (2a) (5 mol %) with BuLi (10 mol %) at 50 C for 6 h in hexane, giving the cross-dimers in 99% yield ((E)-4,5-dimethyl-1-phenylhexa-1,4-diene (3a)/(E)-4,5-dimethyl-1-phenylhexa-2,4-diene (3b)/isomers = 84/9/7). Because neither 2a nor BuLi separately catalyzes the cross-dimerization and reduction of 2a with BuLi in the presence of naphthalene produces [Ru(eta6-naphthalene)(eta4-1,5-COD)] (1a), the active species in this catalysis is considered to be a Ru(0) compound. Interestingly, this in situ reduction method of Ru(II) using BuLi can be applied to the cross-dimerization using an ester such as methyl acrylate. Alternatively, an air-stable Ru(II) complex having a labile arene ligand such as [RuCl2(eta6-anisole)]2 (5c) (5 mol %) with Na2CO3 (40 mol %) in the presence of 1,5-COD (20 mol %) at 100 C for 6 h in 2-butanol also catalyzes the same cross-dimerization in 62% yield. These protocols provide facile methods for production of unsaturated linear compounds by the cross-dimerization using air-stable Ru(II) catalyst precursors.

Novel ruthenium-catalyzed cross-carbonylation of alkynes and 2-norbornenes to hydroquinones

Unsymmetrically substituted hydroquinones were obtained in high yields by the novel ruthenium-catalyzed cross-carbonylation of alkynes and 2-norbornenes. For example, treatment of 4-octyne and 2-norbornene with 2 mol % Ru3(CO)12 in N-methylpiperidine under 60 atm of carbon monoxide at 140C for 20 h gave the corresponding hydroquinone, 4,5-dipropyltricyclo[6.2.1.02,7]undeca-2(7),3,5-triene-3,6-diol, in 85% yield. The reaction apparently involves a maleoylruthenium intermediate which is generated by the reaction of an alkyne and two molecules of carbon monoxide on the ruthenium.

Synthesis and characterization of half-sandwich ruthenium(II) complexes with N-alkyl pyridyl-imine ligands and their application in transfer hydrogenation of ketones

A series of new arene ruthenium(II) complexes were prepared by reaction of ruthenium(II) precursors of the general formula [(eta6-arene)Ru(mu-Cl)Cl]2 with N,N?-bidentate pyridyl-imine ligands to form complexes of the type [(eta6-arene)RuCl(C5H4N-2-CH=N-R)]PF6, with arene?=?C6H6, R?=?iso-propyl (1a), tert-butyl (1b), cyclohexyl (1c), cyclopentyl (1d) and n-butyl (1e); arene?=?p-cymene, R?=?iso-propyl (2a), tert-butyl (2b). The complexes were fully characterized by 1H NMR and 13C NMR, UV?Vis and IR spectroscopies, elemental analyses, and the single-crystal X-ray structures of 2a and 2b have been determined. The single-crystal molecular structure revealed both compounds with a pseudo-octahedral geometry around the Ru(II) center, normally referred to as a piano stool conformation, with the pyridyl-imine as a bidentate N,N ligand. The activity of all complexes in the transfer hydrogenation of cyclohexanone in the presence of NaOH and iso-propanol is reported, the compounds showing turnover numbers of close to 1990 and high conversions. Complex 2b was also shown to be very effective for a range of aliphatic and cyclic ketones, giving conversions of up to 100?%.

Highly effective DNA photocleavage by novel “rigid” Ru(bpy) 3-4-nitro-and -4-amino-1,8-naphthalimide conjugates

The synthesis of the two novel 1,8-naphthalimideruthenium conjugates Ru-Nap-NO2 and Ru-Nap-NH2 and their photophysical evaluation upon interaction with DNA is reported. Significant changes were seen in both the absorption and emission spectra upon interaction of both conjugates with DNA, from which large binding constants were determined. Moreover, highly, efficient DNA cleavage was observed upon irradiation for 5 min, during which supercoiled DNA was converted to nicked and linear DNA by Ru-Nap-NH2.

Sensitized photodecomposition of organic bisphosphonates by singlet oxygen

During efforts to stabilize metal oxide bound chromophores for photoelectrochemical applications, a novel photochemical reaction has been discovered. In the reaction, the bisphosphonate functional groups -C(PO 3H2)2(OH) in the metal complex [Ru(bpy) 2(4,4?-(C(OH)(PO3H2)2bpy)] 2+ are converted into -COOH and H3PO4. The reaction occurs by sensitized formation of 1O2 by the lowest metal-to-ligand charge transfer excited state(s) of [Ru(bpy) 2(4,4?-(C(PO3H2)2(OH)) 2(bpy))]2+* followed by 1O2 oxidation of the bisphosphonate substituent. A related reaction occurs for the bisphosphonate-based drug, risedronic acid, in the presence of O2, light, and a singlet oxygen sensitizer ([Ru(bpy)3]2+ or Rose Bengal).

A nuclear permeable Ru(II)-based photoactivated chemotherapeutic agent towards a series of cancer cells: In vitro and in vivo studies

Ru(ii) polypyridyl complexes which can undergo photo-induced ligand dissociation and DNA covalent binding are considered as potential photoactivated chemotherapeutic (PACT) agents. Herein four pyridine-2-sulfonate (py-SO3-) ligand based Ru(ii) complexes [Ru(N-N)2(py-SO3)]+ (1-4) were synthesized and studied. All the complexes can undergo fast py-SO3- ligand dissociation and DNA covalent binding upon visible light irradiation. However, only complex 4 exhibited high photo-induced anticancer activities towards a series of cancer cells, with half maximal inhibitory concentration (IC50) values in 100-300 nM regions and phototoxicity index (PI) values of about 100. In particular, complex 4 can also kill cisplatin resistant SKOV-3 and A549 cancer cells with IC50 values in 200-400 nM regions and PI values of about 50, which should be the first report of Ru(ii) based PACT agents that are also effective towards cisplatin resistant cancer cells. Complex 4 exhibited much higher cell uptake and nuclear accumulation levels, which may be the main reasons for its high anticancer activities. The in vivo anticancer experiments indicated that complex 4 can inhibit tumor growth significantly with fewer side effects. Our results may provide guidelines for developing novel photoactivatable Ru(ii) anticancer agents.

Mono- and dinuclear ruthenium complexes of bridging ligands incorporating two di-2-pyridylamine motifs: Synthesis, spectroscopy and electrochemistry

Mono- and dinuclear ruthenium(II) complexes of six bridging ligands that contain a central arene (phenyl, naphthalenyl or biphenyl) core to which are attached two di-2-pyridylamine groups have been prepared. These complexes possess six-membered chelate rings. Full assignments of their 1H NMR spectra are described which provides insight into the comformations of the ligands in these complexes. The extent of metal-metal communication in the dinuclear complexes was probed by electrochemical measurements and related to metal-metal distances.
