A 1: 1: 1 stoichiometric reaction between CrO3, aqueous HF, and quinaldine affords orange crystalline quinaldinium fluorochromate(VI) (QnFC) (C10H9NH[CrO3F]) in 99.4% isolated yield. A highly efficient, simple, chemoselective, and environmentally benign procedure for QnFC (3 mol%) catalyzed oxidation of primary and secondary alcohols to aldehydes and ketones using 1.1 equiv of H5IO6 under solvent-free conditions is described.

Thermal catalytic hydrosilylation of conjugated dienes with triethylsilane in the presence of tricarbonyl(o-xylene)metal (metal = Cr, Mo, W) complexes
Kayran, C; Rouzi, P (Walter de Gruyter GmbH, 2001-11-01)
The thermal catalytic hydrosilylation of 1,3-butadiene (1), trans-2-methyl-1, 3-pentadiene (2), 2,3-dimethyl-1,3-butadiene (3), and isoprene (4), with triethylsilane were studied in the presence of M(CO)(3) (o-xylene) (M = Cr, Mo, W) complexes in polar and nonpolar solvents such as tetrahydrofuran, hexane and toluene. Mo(CO)(3) (o-xylene) was found to be the only active catalyst for the hydrosilylation of 3 with triethylsilane, which gave 1-triethylsilyl-2,3-dimethyl-2-butene (3a), as hydrosilylated product...
Experimental investigation of drag reduction effects of polymer additives on turbulent pipe flow using ultrasound Doppler velocimetry
Zeybek Vural, Serife; Bayram, Göknur; Uludağ, Yusuf (The Scientific and Technological Research Council of Turkey, 2014-01-01)
Drag reduction in fully developed turbulent pipe flow with 4 concentrations (200 to 500 wppm or mg/kg) of low molecular weight sodium carboxymethylcellulose (CMC) in aqueous solutions was investigated experimentally. Drag reduction was determined by pressure drop measurements. Maximum drag reduction achieved was 22% using 500 wppm CMC solution. To observe the impact of the presence of CMC on the flow, ultrasound Doppler velocimetry (UDV) was employed to monitor the instantaneous velocity distributions. Expe...
Aryl butenoic acid derivatives as a new class of histone deacetylase inhibitors: synthesis, in vitro evaluation, and molecular docking studies
Esiyok, Peruze Ayhan; Seven, Ozlem; Eymur, Guluzar; Tatar, Gamze Bora; DAYANGAÇ ERDEN, DİDEM; YELEKÇİ, Kemal; YURTER, HAYAT; Demir, Ayhan Sıtkı (The Scientific and Technological Research Council of Turkey, 2014-01-01)
New aryl butenoic acid derivatives have been synthesized by combining hydroxy- or methoxy-substituted phenyl rings as the capping group, with a double bond in the short linker as well as metal binding groups, enoic ester, and salts bearing either methyl or morpholine. These compounds have been shown to possess promising histone deacetylase inhibition activities via in vitro fluorometric assay and molecular docking studies.
ANODIC POTENTIAL HOMO ENERGY RELATIONS OF FLUORENE DERIVATIVES
SEN, S; CELEBI, N; TURKER, L; Önal, Ahmet Muhtar (Wiley, 1993-09-01)
Anodic oxidation peak potentials (E(p,a)) of some fluorene derivatives were measured on a Pt-degrees electrode versus Ag-degrees/Ag+ in acetonitrile-TBAFB by cyclic voltammetry. The highest occupied molecular orbital (HOMO) energies of the compounds were calculated within the Huckel molecular orbital (HMO) framework. The measured E(p,a) values were correlated to theoretical HOMO energies with a linear regression model.
Polystyrene-b-poly(2-vinyl phenacyl pyridinium) salts as photoinitiators for free radical and cationic polymerizations and their photoinduced molecular associations
Taskin, Omer Suat; Erel Göktepe, İrem; Khan, Muhammad Alyaan Ahmed; Pispas, Stergios; Yağcı, Yusuf (Elsevier BV, 2014-07-01)
Polystyrene-b-poly(2-vinyl phenacyl pyridinium hexafluorophosphate) (PS-b-PVPP) was synthesized by reacting polystyrene-b-poly(2-vinyl pyridine) prepared by living anionic polymerization with phenacyl bromide followed by counter anion exchange reaction. The ability of PS-b-PVPP to act as a photoinitiator for both free radical and cationic polymerizations is demonstrated. In the free radical polymerization, the initiation step involves the decay of the excited state of the salt with homolytic bond rupture of...
