The preparation of ruthenium(0) nanoclusters supported on hydroxyapatite and their characterization by a combination of complementary techniques are described. The resultant ruthenium(0) nanoclusters provide high activity and reusability in the complete hydrogenation of aromatics under mild conditions (at 25 degrees C and with 42 psi initial H(2) pressure).

Aminopropyltriethoxysilane stabilized ruthenium(0) nanoclusters as an isolable and reusable heterogeneous catalyst for the dehydrogenation of dimethylamine-borane
Zahmakiran, Mehmet; Tristany, Mar; Philippot, Karine; Fajerwerg, Katia; Özkar, Saim; Chaudret, Bruno (2010-01-01)
The preparation of Ru(0) nanoclusters stabilized by 3-aminopropyltriethoxysilane and their characterization by a combination of complementary techniques are described. These new Ru(0) nanoclusters provide high activity and unprecedented reusability as a heterogeneous catalyst in the dehydrogenation of dimethylamine-borane.
Ruthenium(0) Nanoparticles Supported on Multiwalled Carbon Nanotube As Highly Active Catalyst for Hydrogen Generation from Ammonia-Borane
Akbayrak, Serdar; Özkar, Saim (2012-11-01)
Ruthenium(0) nanoparticles supported on multiwalled carbon nanotubes (Ru(0)@MWCNT) were in situ formed during the hydrolysis of ammonia-borane (AB) and could be isolated from the reaction solution by filtration and characterized by ICP-OES, XRD, TEM, SEM, EDX, and XPS techniques. The results reveal that ruthenium(0) nanoparticles of size in the range 1.4-3.0 nm are well-dispersed on multiwalled carbon nanotubes. They were found to be highly active catalyst in hydrogen generation from the hydrolysis of AB wi...
Organocatalytic Enantioselective Synthesis of Dihydronaphthofurans and Dihydrobenzofurans: Reaction Development and Insights into Stereoselectivity & Design and Synthesis of Heterogeneous Recyclable Organocatalysts
SUSAM, Zeynep Dilşad; Tanyeli, Cihangir; Department of Chemistry (2022-11-18)
The first part of thesis comprises Friedel-Crafts/substitution, which is the most common and widely used C-C bond forming reaction in synthetic organic chemistry. Applications of these reactions in domino type reactions are trending topic in organocatalytic studies in the recent years. These types of reactions are used to perform dihydrobenzofuran (DHB) and dihydronaphthofuran (DHN) skeletons, which are very important pharmaceutical precursors. In this study, it was chosen as the key step in domino reaction...
Asymmetric synthesis of norbornene based 1,4-amino alcohol derivatives and applications in asymmetric transformations
Sünbül, Murat; Tanyeli, Cihangir; Department of Chemistry (2005)
The asymmetric synthesis of cis-1,4-aminoalcohols with norbornene backbone was performed starting with simple and cheap anhydride 30. Quinine-mediated desymmetrization of anhydride 30 with methanol resulted in (2S,3R)-(-)-cis-hemiester 31 (98% e.e.). Chemoselective amination with HMPTA and NH4OH followed by LAH reduction afforded (2S,3R)-(+)-36 and (2S,3R)-(-)-37, respectively. The amidoester (2S,3R)-(-)-32 was transformed into chiral ligand (2S,3R)-(-)-35 with Grignard reaction followed by LAH reduction. T...
Spectrophotometric and amperometric biosensors based on conducting polymers of 1-Benzyl-2,5-DI(Thiophen-2-YL)-1H-Pyrrole and (4,7-Dithien-2-YL-2,1,3-Benzothiadiazole)
Tanrıverdi, Simla; Toppare, Levent Kamil; Timur, Suna; Department of Polymer Science and Technology (2012)
In this thesis, two different biosensors based on conducting polymers of (4,7-dithien-2-yl-2,1,3-benzothiadiazole) (TBTD) and 1-benzyl-2,5 di(thiophene-2-yl)-1H-Pyrrole (SNBS) were prepared. Electrochemical technique was used for polymerization of conducting polymers and two different immobilization techniques were used for immobilizing enzyme into the conducting polymer matrices. The proposed biosensors were characterized and optimized. Optimum pH, thickness, enzyme amount were determined and linearity, re...
