Chelating mono- and di-pyridyl functionalized beta-diketones, viz. 1-phenyl-3-(2-pyridyl) propane-1,3-dione (pppdH) and 1,3-di(2-pyridyl)propane-1, 3-dione (dppdH) ligands yielded new water soluble eta6-arene ruthenium(II) complexes of the formulation [(eta6-arene) Ru(kappa2-N-O-pppdH)Cl] + (arene = C6H 6 1, p- i PrC6H4Me 2, C 6Me6 3) and [(eta6-arene)2Ru 2(kappa4-N-O-dppd)Cl2] + (arene = C6H6 4, p- i PrC6H4Me 5, C6Me6 6), as their (complexes 1-4, 6) PF6 salt or (complex 5) BF4 salt. The complexes were obtained by treatment of respective precursors, [(eta6-arene)Ru(mu-Cl)Cl]2 (arene = C6H6, p- i PrC6H 4Me, C6Me6) in 1:2 and 1:1 molar ratio with pppdH and dppdH in the presence of NH4PF6/NH 4BF4. All the complexes have been characterized on the basis of FT-IR and NMR spectroscopic data as well as by elemental analysis. Molecular structures of representative complexes 2, 5 and 6 have been confirmed by single crystal X-ray diffraction studies. The ‘O-C-C-C-O’ fragment of the coordinated ligand (pppdH) is neutral in complexes 1-3 and that of the dppdH ligand existed as a neutral as well as concomitantly uninegative fashion in complexes 4-6 due to the delocalization of pi-electrons.

The bonding modes of the ligand di-2-pyridyl ketoxime towards half-sandwich arene ruthenium, Cp*Rh and Cp*Ir complexes were investigated. Di-2-pyridyl ketoxime {pyC(py)NOH} react with metal precursor [Cp*IrCl2]2to give cationic oxime complexes of the general formula [Cp*Ir{pyC(py)NOH}Cl]PF6(1a) and [Cp*Ir{pyC(py)NOH}Cl]PF6(1b), for which two coordination isomers were observed by NMR spectroscopy. The molecular structures of the complexes revealed that in the major isomer the oxime nitrogen and one of the pyridine nitrogen atoms are coordinated to the central iridium atom forming a five membered metallocycle, whereas in the minor isomer both the pyridine nitrogen atoms are coordinated to the iridium atom forming a six membered metallacyclic ring. Di-2-pyridyl ketoxime react with [(arene)MCl2]2to form complexes bearing formula [(p-cymene)Ru{pyC(py)NOH}Cl]PF6(2); [(benzene)Ru{pyC(py)NOH}Cl]PF6(3), and [Cp*Rh{pyC(py)NOH}Cl]PF6(4). In case of complex 3 the ligand coordinates to the metal by using oxime nitrogen and one of the pyridine nitrogen atoms, whereas in complex 4 both the pyridine nitrogen atoms are coordinated to the metal ion. The complexes were fully characterized by spectroscopic techniques.

[Ru(p-cymene)Cl2]2-catalyzed 1,4-addition reactions between arylboronic acids and butyl acrylate and acrylamide in the presence of phenols were investigated, good to excellent yields were obtained. The addition of phenols remarkably promoted the protonolysis and inhibited the beta-H elimination of the 1,4-addition intermediates, and also efficiently suppressed the protonolysis of arylboronic acids.

15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru, belongs to ruthenium-catalysts compound, is a common compound. In a patnet, once mentioned the new application about 15746-57-3, Recommanded Product: Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II)

Three Ru(II) polypyridine complex isomers (Ru-2-DP, Ru-3-DP and Ru-5-DP) have been synthesized using phenanthroline-based isomers containing 4-(2,2-diphenyl-vinyl)-phenyl unit. Their photophysical properties are systematically investigated. Notably, three coordination isomers exhibit much longer triplet lifetimes compared to the model complex [Ru(bpy)2(Phen)]2+. The density function theory calculations reveal that the extension of triplet lifetimes is attributed to the establishment of an excited-state equilibrium between the intraligand (3IL) state and the metal-to-ligand charge-transfer (3MLCT) state. In aggregates, Ru-2-DP shows an interesting aggregation-induced phosphorescence enhancement (AIPE) property. The phosphorescence intensity of Ru-2-DP increases by 16.2-fold from acetonitrile solution to aggregated state. However, Ru-3-DP and Ru-5-DP are AIPE-inactive. Single-crystal analyses show substituent position has a dramatic effect on intramolecular steric hindrance, leading to different molecular conformation and packing pattern. Using three coordination isomers as triplet sensitizers for triplet-triplet annihilated (TTA) upconversion, Ru-3-DP and Ru-5-DP display obvious upconversion properties, but it’s quite the opposite for Ru-2-DP. Experimental data demonstrate 3- and 5-positions of phenanthroline, especially 3-position, are beneficial to enhance intersystem crossing and triplet-triplet energy transfer and for the resulting upconverted efficiency enhancement. This work definitely suggests that minor structural change may have major effects upon the solid-state spectroscopic properties and TTA upconversion performances, which provides a rational basis for designing excellent solid phosphorescent materials and triplet sensitizers.

The use of Ru complexes in light-mediated treatment of cancer (i.e. Photodynamic Therapy ? PDT) has recently become extremely relevant with the entry into clinical trials of the first complex of this class against bladder cancer in the very near future. Herein, we report on the potential application as PDT agents of two inert Ru(II) polypyridyl complexes bearing a nitrile containing dppz ligand and two bipy or phen ancillary ligands for 1 and 2, respectively (dppz = dipyrido[3,2-a:2?,3?-c]phenazine, bipy = 2,2?-bipyridine, phen = 1,10-phenathroline). More specifically, a full characterization of the novel compound 2 was first performed. The distribution coefficients (log D) and1O2quantum yields in two solvent systems and at two irradiation wavelengths were then determined for both compounds. The phototoxicity of complexes 1 and 2 was evaluated on cervical cancer HeLa cells and on non tumorigenic retinal pigment epithelial (RPE1-hTERT) cells. None of the complexes was found to be phototoxic. In vitro fluorescence microscopy indicated a scarce cellular uptake for 2. The lack of biological activity for complexes 1 and 2 highlights that more investigations are required in order to understand the relationship between structure and biological activity for this class of compounds.
