An investigation on the synthesis of new molecular architectures from the cyclotrimerisation of exo- and endo-benzotricyclo[,5)]nonene
Dastan, A; Uzundumlu, E; Balcı, Metin; Fabris, F; De Lucchi, O (Wiley, 2004-01-01)
We have performed an investigation on the cyclotrimerisation of molecules having exo- and endo-benzotricyclo[,5)]nonene skeletons (3 and 4) with the aim of producing their respective cyclotrimers 2 that feature unusual geometries and electronic properties. Activation towards the cyclotrimerisation reaction was performed using the vic-bromostannyl vinyl derivatives and was accomplished under copper-mediated or palladium-catalysed reaction conditions. While the exo isomer 3 proved to be quite reactiv...
The preparation and characterization of zeolite confined rhodium(0) nanoclusters: a heterogeneous catalyst for the hydrogen generation from the methanolysis of ammonia-borane
Çalışkan, Salim; Özkar, Saim; Department of Chemistry (2010)
Among the new hydrogen storage materials, ammonia borane (AB) appears to be the most promising one as it has high hydrogen content, high stability, and being environmentally benign. Dehydrogenation of AB can be achieved via hydrolysis, thermolysis or methanolysis. Methanolysis of AB eliminates some drawbacks of other dehydrogenation reactions of AB. The use of colloidal and supported particles as more active catalyst than their bulky counterparts for the hydrolysis of AB implies that reducing the particle s...

There is no significant disagreement about the basic selection rules operating in the ferro-ordered (δ) and antiferro-ordered (γ) phases of the ammonium halides. The effects of residual disorder just below the transition temperature (Tc) are still treated differently by different research groups and therefore this remains a subject of some interest. In this study it will be shown how our approaches lead to assignments of the modes observed in the disordered β - phase, Raman spectrum at temperatures just be...
The synthesis and characterization of new metal-free and metallo phthalocyanines substituted with four dithiatetraoxa macrocyclic moieties
Kantekin, Halit; Rakap, Murat; Misir, Mirac Nedim; Goek, Halil Zeki; Acar, Irfan (Informa UK Limited, 2007-01-01)
New metal-free phthalocyanine ( 7) fused symmetrically in peripheral positions with four dithiatetraoxa macrocycles, has been synthesized by cyclotetramerization of the isoindoline-diimine derivative of macrocyclic 6. Metallophthalocyanine ( 8) was synthesized by reaction of phthalonitrile derivative ( 5) with anhydrous nickel( II) chloride. The new compounds were characterized by elemental analysis, H-1 and C-13-NMR, IR UV-Vis and mass spectroscopies.
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%).
