Condensation reaction of 2,9-dicarboxaldehyde-1,10-phenanthroline with 2-aminoethanol followed by NaBH4 reduction yielded the polydentate Schiff base ligand 2,9-bis(ethanolamine)-1,10-phenanthroline in its reduced form. This ligand was characterized by elemental analysis, LC-MS, IR, UV-Vis and NMR spectroscopy. Reaction of the reduced Schiff base ligand with aqueous solution of cobalt(II) chloride affords 2,9-bis(ethanolamine)-1,10-phenanthrolinechlorocobalt(II) chloride in high yield. Single crystals of the cobalt(II) complex were obtained from the crystallization in ethanol and its structure was elucidated by X-ray structural analysis. The cobalt(II) complex ion was found to be seven-coordinated in a pentagonal bipyramidal geometry, whereby cobalt(II) ion is surrounded by the six donor atoms in the ligand molecule and a chloride ion.

Reaction of Metal-Carbene Complexes with Cyclobutenediones: The First General C-C Bond Insertion Reaction for Fischer Carbene Complexes Zora, Metin (American Chemical Society (ACS), 1993-01-01) Alkylcarbene-chromium complexes react with cyclobutenediones to give 2-alkoxy-4-cyclopentene-1,3-diones in moderate yield, accompanied by varying amounts of 4-cyclopentene-1,3-dione derivatives which result from reduction of the initial product by the chromium byproduct. The reaction is general for a variety of cyclobutenedione derivatives with alkoxy, alkyl, or aryl substituents. The major products of the reaction between arylcarbene complexes and cyclobutenediones are 5-alkylidenefuranone derivatives. A m...
Synthesis and characterization of the [Ni6Ge13(CO)(5)](4-) and [Ge9Ni2(PPh3)](2-) Zintl ion clusters Nalbant Esentürk, Emren; Eichhorn, B (Elsevier BV, 2006-01-23) Reactions between K4Ge9, Ni(CO)(2)(PPh3)(2), and 2,2,2-crypt in ethylenediamine solutions give two different products depending on reaction conditions. The [Ni6Ge13(CO)(5)](4-) ion (1) is formed at low temperatures (similar to 40 degrees C) and short reaction times whereas the [Ge9Ni2(PPh3)](2-) ion (2) forms at higher temperatures (similar to 118 degrees C). Both complexes were isolated as [K(2,2,2-crypt)](+) salts and characterized by single-crystal X-ray diffraction, electrospray mass spectrometry (ESI-M...
Synthesis and electrochemistry of Group 6 tetracarbonyl (N,N '-bis(ferrocenylmethylene)ethylenediamine)metal(0) complexes Kocak, F. Sanem; Kavakli, Cuneyt; Akyol, Ceyhun; Önal, Ahmet Muhtar; Özkar, Saim (Elsevier BV, 2006-11-15) Thermal substitution reaction of Cr(CO)4(η2:2-1,5-cyclooctadiene), Mo(CO)4(η2:2-norbornadiene), and W(CO)5(η2-bis(trimethylsilyl)ethyne) with N,N′-bis(ferrocenylmethylene)ethylenediamine (bfeda) yields M(CO)4(bfeda) complexes which could be isolated from the reaction solution and characterized by elemental analysis, MS, IR, and NMR spectroscopy. In the case of tungsten, W(CO)5(bfeda) is formed as intermediate and then undergoes the ring closure reaction yielding the ultimate product W(CO)4(bfeda). The elect...
Synthesis, characterization, and catalytic activity of supported molybdenum Schiff base complex as a magnetically recoverable nanocatalyst in epoxidation reaction Moradi-Shoeili, Zeinab; Zare, Maryam; Bagherzadeh, Mojtaba; Özkar, Saim; Akbayrak, Serdar (Informa UK Limited, 2016-01-01) A heterogeneous nanocatalyst was prepared via covalent anchoring of dioxomolybdenum(VI) Schiff base complex on core-shell structured Fe3O4@SiO2. The properties and the nature of the surface-fixed complex have been identified by a series of characterization techniques such as SEM, EDX, XRD, TGA, FT-IR, and VSM. The synthesized hybrid material was an efficient nanocatalyst for selective oxidation of olefins to corresponding epoxides with t-BuOOH in high yields and selectivity. The catalyst could be convenient...
Synthesis and characterization of ruthenium(0) metal nanoparticles as catalyst in the hydrolysis of sodium borohydride Zahmakıran, Mehmet; Özkar, Saim; Department of Chemistry (2005) Sodium borohydride is stable in alkaline solution, however, it hydrolyses and generates hydrogen gas in the presence of suitable catalyst. By this way hydrogen can be generated safely for the fuel cells. All of the catalyst having been used in the hydrolysis of sodium borohydride, with one exception, are heterogeneous. The limited surface area of the heterogeneous and therefore, have limited activity because of the surface area. Thus, the use of metal nanoclusters as catalyst with large surface area is expe...
