An efficient oxidative coupling of thiols to give disulfides via thionitrite (S-nitrosothiol) intermediate is described using trichloronitromethane as an efficient reagent in organic solvents and water. Cysteine and glutathione are converted into the corresponding disulfides in water in high yields.

Generation of aryl radicals from arylboronic acids by manganese(III) acetate: Synthesis of biaryls and heterobiaryls
Demir, Ayhan Sıtkı; Reis, O; Emrullahoglu, M (2003-01-24)
The efficient generation of aryl radicals from arylboronic acids by manganese(III) acetate is described. In aromatic solvents, in situ generated aryl radicals afford the corresponding biaryls in very good yields. This method works selectively, and yields are better than those from similar, previously described methods. Arylboronic acids carrying sensitive functional groups also work efficiently.
Investigation of extraction methodologies for quantitative determination of polycyclic aromatic hydrocarbons in sediments
Topal, Tansel; Tuncel, Semra G.; Department of Chemistry (2011)
The extraction procedures for the determination of polycyclic aromatic hydrocarbons (PAH) concentrations in sediment samples had been developed by using GC-FID and GC-MS. The optimized methods were soxhlet extraction, ultrasonic bath extraction and solid phase micro extraction (SPME). In order to search out the main factors affecting extraction efficiencies of the methods, factorial design was used. The best extraction method was chosen and optimum values for main factors were selected for the development o...
Novel Mesoporous Nanocomposite WOx-Silicate Acidic Catalysts: Ethylene and Diethylether from Ethanol
Varisli, Dilek; Doğu, Timur; DOĞU, GÜLŞEN (2009-11-04)
Solid acid catalysts are extensively used in a number of industrially important catalytic reactions. Here, water-insoluble novel mesoporous solid acid catalysts, with a unique structure composed of WOx nanorods and W nanoballs within an amorphous silicate lattice, were synthesized following a one-pot hydrothermal route. using silicotungstic acid (STA) as the active component. Surface area of these catalysts ire more than 2 orders of magnitude higher than that of pure STA, and they showed very high activity ...
Development of novel analytical methods for selenium, gold, silver and indium determination using volatile compound generation, atom trapping and atomic absorption spectrometry
Arslan, Yasin; Ataman, Osman Yavuz; Department of Chemistry (2011)
A novel analytical technique was developed where gaseous hydrogen selenide formed by sodium tetrahydroborate reduction is transported to and trapped on a resistively heated gold-coated W-coil atom trap for in situ preconcentration. The atom trap is held at 165 ºC during the collection stage and is heated up to 675 ºC for revolatilization; analyte species formed are transported to an externally heated quartz T-tube where the atomization takes place and the transient signal is obtained. For gold, a high volum...
Development of Non-Invasive and Biocompatible Thin Film Micro-Extraction Contact Lens Type Devices Compatible for In Vivo Metabolomics Investigations from Eye Surface
Nalbant, Atakan Arda; Boyacı, Ezel (2019-09-01)
Solid phase microextraction (SPME), is a sampling and samp- le preparation technique in which the extraction of analytes is based on an equilibrium established between a sample and ext- ractive phase coated on a tip of a fiber. Thin film microextraction (TFME) which is a type of SPME provides high analytical sen- sitivity in environmental and biological samples and has gained interest in areas where no other technique can provide solutions. In this study, the aim was to develop biocompatible and flexib-...
