ree nitroxyl radicals are popular in alcohol oxidation reactions as catalysts. The most useful ones are TEMPO (2,2,6,6-tetramethylpiperidinoxyl) derivatives. In this thesis, TEMPO based polymeric catalyst systems were synthesized. The most important property of these catalysts are being homogeneous and recyclable systems. In the synthetic strategy, the monomer systems which are needed for polymerization were synthesized from easily available norbornene derivatives via Mukaiyama and DCC coupling reactions. The resultant one and two TEMPO unit containing systems were polymerized in a controlled way by ROMP (Ring Opening Metathesis Polymerization). The activity test of these new catalysts were done by the oxidation of several primary alcohols. The yields and time for transformation were determined by the help of gas chromatography. All the products were identified by ^-NMR, 13C-NMR, MS and IR spectroscopy.

Synthesis of tempo containing chiral polymers for kinetic resolution of secondary alcohols. Yücel, Ece Ayç; Akdağ, Akın; Department of Chemistry (2020) Optically pure secondary alcohols are important building blocks for the synthesis of chemicals used in pharmaceutical sciences. Kinetic resolution of secondary alcohols through selective oxidation of one enantiomer to the corresponding ketone is a classical and efficient method to obtain enantiopure alcohols. An oxidative kinetic resolution is achieved by exploiting two enantiomers’ unequal rates of oxidation reaction with a chiral reagent or catalyst. The general approach towards a kinetic resolution via a...
Electrochemical and chemical oxidation of K(C2H5OCS2),[Ni(C2H5OCS2)(2)] and [N(C2H5)(4)][Ni(C2H5OCS2)(3)] Dag, O; Önal, Ahmet Muhtar; Isci, H (1996-06-26) Electrochemical and chemical oxidation of (Et-Xan(-)), [Ni(Et-Xan)(2)] and [Ni(Et-Xan)(3)](-) (Et-Xan(-) = C2H5OCS2- have been studied by Cyclic Voltammetry and in situ UV-Vis spectroscopy in acetonitrile at room temperature. Cyclic Voltammograms (CV) of Et-Xan(-) and Ni(Et-Xan)(2) display one (0.00 V) and two (0.35 and 0.80 V) irreversible oxidation peaks, respectively, referenced to Ag/Ag+(0.10 M) electrode. However, CV of Ni(Et-Xan)(3)(-) displays one reversible (-0.15 V) and two irreversible (0.35, 0.80...
Preparation of lead zirconate titanate (Pb(Zr0.52Ti0.48)O-3) by homogeneous precipitation and calcination Oren, EE; Tas, AC (1998-05-06) Aqueous solutions of lead chloride (PbCl2), zirconium oxychloride (ZrOCl2.8H(2)O) and titanium tetrachloride (TiCl4), in appropriate volumetric amounts, were used as the starting materials in the synthesis of phase-pure Pb(Zr0.52Ti0.48)O-3 powders. Preparation of the phase-pure PZT powders were achieved, in the presence of urea (CH4N2O), by the chemical powder synthesis route of homogeneous precipitation.
Synthesis and characterization of a bifunctional amido-thiophene monomer and its copolymer with thiophene and electrochemical properties AK, M; Çırpan, Ali; Yılmaz, Fatih; YAGCI, Y; Toppare, Levent Kamil (2005-05-01) A bifunctional amido-thiophene namely hexamethylene (bis-3-thiophene acetamide) (HMTA) was synthesized by the reaction of 3-thiophene acetic acid with hexamethylene diamine. Copolymerization in the presence of thiophene was achieved electrochemically in tetrabutylammonium tetrafluoroborate/acetonitrile (TBAFB/AN). Spectroelectro-chemical analysis of the resulting copolymer [P(HMTA-co-Th)] reflected electronic transitions at 505 nm, 740 nm and similar to 1000 nm, revealing pi to pi* transition, polaron and b...
