As part of our efforts to develop ruthenium nitrosyl compounds for use as nitric oxide delivery agents, a new six coordinate {RuNO}6 compound, [Ru(NO)(bpb)Cl] (bpb = N,N?-bis(2-pyridinecarboxamide)-1,2-benzene dianion) was prepared from the reaction between [Ru(NO)Cl(H2O) 2] and N,N?-bis(2-pyridine carboxamide)-1,2-benzene. We report here the characterization of this new compound by 1H, 13C, HH COSY, HMQC and HMBC NMR spectroscopy, IR spectroscopy (nuNO = 1867 cm-1) and ESI-MS (M + Na+ 505.9).

Application of 15746-57-3, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru. In a patent, introducing its new discovery.

The series of complexes [Ru(bpy)3-n(btz)n][PF 6]2 (bpy = 2,2?-bipyridyl, btz = 1,1?-dibenzyl-4,4?-bi-1,2,3-triazolyl, 2n = 1, 3n = 2, 4n = 3) have been prepared and characterised, and the photophysical and electronic effects imparted by the btz ligand were investigated. Complexes 2 and 3 exhibit MLCT absorption bands at 425 and 446 nm respectively showing a progressive blue-shift in the absorption on increasing the btz ligand content when compared to [Ru(bpy)3][Cl]2 (1). Complex 4 exhibits a heavily blue-shifted absorption spectrum with respect to those of 1-3, indicating that the LUMO of the latter are bpy-centred with little or no btz contribution whereas that of 4 is necessarily btz-centred. DFT calculations on analogous complexes 1?-4? (in which the benzyl substituents are replaced by methyl) show that the HOMO-LUMO gap increases by 0.3 eV from 1?-3? through destabilisation of the LUMO with respect to the HOMO. The HOMO-LUMO gap of 4? increases by 0.98 eV compared to that of 3? due to significant destabilisation of the LUMO. Examination of TDDFT data show that the S 1 states of 1?-3? are 1MLCT in character whereas that of 4? is 1MC. The optimisation of the T 1 state of 4? leads to the elongation of two mutually trans Ru-N bonds to yield [Ru(kappa2-btz)(kappa1-btz) 2]2+, confirming the 3MC character. Thus, replacement of bpy by btz leads to a fundamental change in the ordering of excited states such that the nature of the lowest energy excited state changes from MLCT in nature to MC.

The complexes LnM-CN-Ag-CN with LnM=Cp(dppe)Fe or Cp(PPh3)2Ru are available from [Ag(CN)2]- and [LnM]+ or LnM-CN. They are precursors of [LnM-CN-Ag-NC-MLn]+. Likewise the trinuclear complexes [LnM?-CN-Ag-NC-M?Ln]+ with LnM?=(TPA)Cu and cis-(bpy)2FeCN have been prepared. Irrespective of the CN attachment in the starting materials the cyanide-bridged compounds always contain M-CN-Ag arrays, i.e. silver-isocyanide coordination, thereby proving the lability of the silver-cyanide linkage. Electrochemical measurements have shown that there is no electronic communication between the outer metal centers in the trinuclear complexes.

Two ruthenium acetylide complexes [Ru]C?C(C5H 3RN) (1a, R = H; 1b, R = Me; [Ru] = Cp(PPh3) 2Ru) containing 2-pyridyl groups are prepared and their chemical reactivities are explored. Protonation of the ruthenium acetylide complex 1a with HBF4 takes place at both the nitrogen atom and Css, giving the dicationic pyridiniumvinylidene complex {[Ru]=C=C(H)(C5H 4NH)}(BF4)2 (3a). Addition of BF3 to la yields the Lewis acid/base adduct [Ru]OC(C5H4N? BF3) (4a). In the presence of moisture both complexes 3a and 4a in solution transform into the cationic heterocyclic carbene complex {[Ru]=C(O)CH2(C5H4N?BF2)}BF4 (6a), for which the structure is confirmed by X-ray structure determination. The formation of 6a involves the intermediate {[Ru]=C=C(H)(C5H 4N?BF2OH)}BF4 (5a), characterized by spectroscopic methods. DFT calculations show that the Gibbs free energy change of the exothermic transformation of 5a to 6a is -20.59 kcal/mol. N-Alkylation reactions of 1b with two alkyl bromides BrCH2R? (R? = CH=CHCO2Me and CO2Me) yield two pyridiniumacetylide complexes {[Ru]C? C(C5H3MeNCH2R?)} Br (7b, R? = CH=CHCO2Me; 7c, R? = CO2Me, respectively). Complex 7c, characterized by X-ray structure determination, undergoes further protonation to give the pyridiniumvinylidene complex {[Ru]=C=C(H)(C5H4NCH2R?)2+ (8c). Interestingly, the acetylide complex 7b undergoes a C-C coupling reaction of the acetylic Css with the C=C double bond to give the vinylidene complex 9b, characterized also by X-ray structure determination.

A new method for the stereoselective metal-free syn-dihydroxylation of electron-rich olefins is reported, involving reaction with TEMPO/IBX in trifluoroethanol (TFE) or hexafluoroisopropanol (HFIP) and the addition of a suitable nucleophile. Orthogonally protected syn 1,2-diols were obtained with high levels of diastereocontrol, and these products were selectively deprotected and selectively functionalized into synthetically useful compounds.

The activity and stereoselectivity of phosphane- and N-heterocyclic carbene (NHC)-containing ruthenium benzylidene complexes have been evaluated in macrocyclic ring-closing olefin metathesis to produce unsaturated lactones and lactams. The success of the macrocyclization depends on the nature of the ligand (phosphane or N-heterocyclic carbene) on the ruthenium center and on the NHC properties. As for stereoselectivity, E/Z ratios seem to be influenced not only by the nature of the ruthenium catalyst but also by the thermodynamic stabilities of the resulting unsaturated macrocycles, as confirmed by theoretical results. The synthesis of 14-and 15-membered macrolactones and macrolactams by ruthenium-catalyzed ring-closing metathesis is investigated. The reaction outcome is influenced both by the nature of the catalyst and the diene substrate.

Both the sensitizers were tested in dye-sensitized solar cells using two different redox electrolytes.
