The ruthenium(B) complex [Ru(bpy)(2)L](PF6)(2), where bpy is 2,2'-bipyridine and L is 1,5-dihydro-2-H-cyclopenta[1,2-b:5,4-b']dipyridine-2-one, was synthesized from the reaction of cis-Ru(bpy)(2)Cl-2 center dot 2H(2)O with L, and isolated as the hexafluorophosphate salt. The structure of L was unequivocally elucidated by single-crystal X-ray diffraction analysis. The new ruthenium(II) complex was thoroughly characterized by H-1 and C-13 NMR spectroscopy, along with FTIR, UV-Vis and LC MS/MS Triple Quadrupole Mass spectroscopy and elemental analysis. The catalytic activity of [Ru(bpy)(2)L](PF6)(2) was tested in the transfer hydrogenation of various ketones in 2-propanol as both the solvent and hydrogen donor. The usage of [Ru(bpy)(2)L](PF6)(2) for the formation of a dye sensitized solar cell is also presented.

A new antiaromatic compound: 1,4-biphenylenequinone synthesis and trapping reactions: can a quinone unit stabilize the cyclobutadiene? Kilic, H; Balcı, Metin (2001-12-03) The photooxygenation of 4a,8b-dihydrobiphenylene affords an endoperoxide. NEt3-catalyzed rearrangement of this endoperoxide gave the corresponding hydroxy enone, while the CoTPP-catalyzed rearrangement afforded a bisepoxide. MnO2 oxidation of hydroxy enol leads to 4a,8b-dihydrobiphenylene-1,4-dione. The NIBS bromination of this dione produces mono- and dibromides. NEt3-supported elimination of monobromide and zinc elimination of dibromide afforded the target compound, 1,4-biphenylenequinone, which was trapp...
A new and stereospecific synthesis of an inositol analogue: bis-homoinositol Kara, Y; Balcı, Metin (2003-03-17) The photooxygenation of trans-8-(acetyloxy)bicyclo[4.2.0]octa-2,4-dien-7-yl acetate afforded the bicyclic endoperoxide. Reduction of the endoperoxide with thiourea followed by acetylation gave the corresponding tetraacetate. The KMnO4 oxidation of the tetraacetate followed by acetylation gave dihydroxytetraacetate Ammonolysis of tetraacetate afforded the bis-homoinositol, bicyclo[4.2.0]octane-2,3,4,5,7,8-hexol.
Organometallic ruthenium, rhodium and iridium complexes containing a P-bound thiophene-2-(N-diphenylphosphino)methylamine ligand: Synthesis, molecular structure and catalytic activity AYDEMİR, MURAT; BAYSAL, AKIN; MERİÇ, NERMİN; KAYAN, CEZMİ; Gumgum, Bahattin; Özkar, Saim; ŞAHİN, Ertan (2011-07-01) Reaction of Ph2PNHCH2-C4H3S with [Ru(eta(6)-p-cymene)(mu-Cl)Cl](2), [Ru(eta(6)-benzene)(mu-Cl)Cl](2), [Rh(mu-Cl)(cod)](2) and [Ir(eta(5)-C5Me5)(mu-Cl)Cl](2) yields complexes [Ru(Ph2PNHCH2-C4H3S)(eta(6)-p-cymene)Cl-2], 1, [Ru(Ph2PNHCH2-C4H3S)(eta(6)-benzene)Cl-2], 2, [Rh(Ph2PNHCH2-C4H3S)(cod)Cl], 3 and [Ir(Ph2PNHCH2-C4H3S)(eta(5)-C5Me5)Cl-2], 4, respectively. All complexes were isolated from the reaction solution and fully characterized by analytical and spectroscopic methods. The structure of [Ru(Ph2PNHCH2-...
Characterization and modulation by drugs and other effectors of bovine liver microsomal flavin monoxygenase(fmo) Başer, Deniz Fulya; Adalı, Orhan; Department of Biochemistry (2004) The flavin-containing monooxygenases (FMO; E.C.1.14.13.8) are microsomal NADPH and oxygen-dependent flavoprotein enzymes that catalyze the oxidation of a wide variety of xenobiotics, including drugs and environmental toxicants. Nucleophiles containing nitrogen, sulfur, phosphorus and selenium heteroatoms are the substrates of FMO. Bovine liver microsomal FMO enzyme activity was characterized using methimazole as substrate, which is a highly specific substrate for FMO. From 12 different bovine liver samples,...

The hydro-peroxy endoperoxide was reduced with dimethylsulfide–titanium tetraisopropoxide to produce (±)-anti-2,3-dioxabicyclo[2.2.2]oct-7-en-5-ol. The highly efficient enantioselective resolution of the racemic (±)-anti-2,3-dioxabicyclo[2.2.2]oct-7-en-5-ol was accomplishedwithCandida cylindracealipase (CCL) to produce the enantiomerically enriched alcohol and the corresponding acetate: Thecleavage of th...
