One-electron constant potential electrolysis of tetraethylammonium tris(ethylxanthato)nickelate(II), (NEt4 )[Ni(S2COEt)(3)] and bis(ethylxanthato)nickel(II), Ni(S-2 COEt) (2) , at their lowest oxidation peak potentials, were followed by in situ UV-VIS spectrophotometry, in acetonitrile at 253 K. In both cases [Ni-III (S2COEt)(3)] complex formed and detected by its electronic absorption and EPR spectra. [Ni-III (S2COEt)(3)] slowly disproportionated to Ni(S2COEt)(2) and the dimer of the oxidized ethylxanthate ligand, (S2COEt)(2) , with a second-order rate law.

A new and efficient chemoenzymatic route to both enantiomers of alpha '-acetoxy-alpha-methyl and gamma-hydroxy-alpha-methyl cyclic enones Demir, Ayhan Sıtkı; Findik, H; Kose, E (Elsevier BV, 2004-03-08) A chemoenzymatic synthesis of both enantiomers of the pharmacologically interesting alpha'-acetoxy-alpha-methyl and gamma-hydroxy-alpha-methyl cyclic enones starting from alpha-methyl-beta-methoxy cyclic enones is reported. Manganese(Ill) acetate-mediated acetoxylation followed by the enzyme-mediated hydrolysis of alpha'-acetoxy enone provides acetoxy enones 1a and 2a and hydroxy enones 1b and 2b with high enantiomeric excesses in good yields. The reduction of the acetoxy and hydroxy enones furnished both e...
Nonlinear effects in proline-thiourea host-guest complex catalyzed aldol reactions in nonpolar solvents Demir, Ayhan Sıtkı; Eymur, Serkan (Elsevier BV, 2010-03-16) An aldol reaction catalyzed by a proline-thiourea host-guest complex in a nonpolar solvent shows excellent nonlinear effects. This proline-thiourea system has the ability to form a hydrogen-bonding network. The enantiomeric excess of proline in a solution can be significantly enhanced by its incorporation with a urea molecule into its solid racemate. This suggests a general and facile route to homochirality, which may be involved in the origin of chirality on earth.
The first enzymatic resolution of quaternary alpha-acetoxy alpha-substituted cyclic ketones Tanyeli, Cihangir; İYİGÜN, Cigdem (Elsevier BV, 2006-04-03) The enantioselective resolution of quaternary alpha-acetoxy alpha-substituted indanone and 1-tetralone derivatives was performed with commercially available enzyme CRL in pH = 8.0 phosphate buffer. Various parameters that would affect the enantoselectivities were tested, and the optimal enzymatic resolution condition was found to afford the enantiomerically enriched quaternary acetoxylated substrates with high ees (varied between 81% and 85%).
ELECTRONIC ABSORPTION AND MAGNETIC CIRCULAR-DICHROISM SPECTRA FOR BINUCLEAR PT2(SO4)4X2N- AND PT2(HPO4)4X2N- IONS IN AQUEOUS-SOLUTION GOKAGAC, G; ISCI, H; MASON, WR (American Chemical Society (ACS), 1992-05-27) Electronic absorption and 7-T magnetic circular dichroism (MCD) spectra in the UV-visible region are reported for the binuclear diplatinum(III) ions: Pt2(SO4)4X2n-, n = 2, X = H2O, NH3; n = 4, X = Cl-, Br-, OH-. Pt2(HPO4)4X2n-, n = 2, X = H2O, Me2S; n = 4, X = Cl-, Br-. Both the absorption spectra and the MCD spectra for complexes with the same axial ligand X are similar for oxo-bridging SO42- or HPO42-. However, the MCD spectra show marked differences depending upon the nature of the X ligand. The mos...
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...
