(+/-)-2-Thienylcarbinols and their O-acetyl derivatives were resolved in reverse separation by CCL and PLE catalysed hydrolysis to afford optically active 2-thienylcarbinols in 35%-99% e.e. that are valuable chiral building blocks, in particular in the synthesis of pheromones and some alkoloid type natural products. Absolute configurations were determined by the correlation of specific rotation values with the literature and by transforming into the corresponding secondary alcohols via reductive desulfurization by Ra-Ni.

Immobilization of dioxomolybdenum(VI) complex bearing salicylidene 2-picoloyl hydrazone on chloropropyl functionalized SBA-15: A highly active, selective and reusable catalyst in olefin epoxidation
Bagherzadeh, Mojtaba; Zare, Maryam; Salemnoush, Taghi; Özkar, Saim; Akbayrak, Serdar (Elsevier BV, 2014-04-05)
A novel organic-inorganic hybrid heterogeneous catalyst system was obtained from the reaction of the molybdenum(VI) complex of salicylidene 2-picoloyl hydrazone with mesoporous silica containing 3-chloropropyl groups prepared by a direct synthetic approach involving hydrolysis and co-condensation of tetraethylorthosilicate (TEOS) and 3-chloropropyltrimethoxysilane in the presence of the triblock copolymer P123 as template under acidic conditions. Characterization of the functionalized materials by X-ray dif...
PLE catalyzed enantiomeric separation of (+/-)-2-furylcarbinols
Tanyeli, Cihangir; Arkin, Ali Hakan; Akhmedov, Idris Mecidoğlu (1997-01-01)
O-Acetyl derivatives of (+/-)-2-furylcarbinols were resolved by PLE catalyzed hydrolysis to afford optically active 2-furylcarbinols in up to 98% e.e. that are valuable chiral building blocks in the synthesis of various biologically active compounds. Enantiomeric excess values were determined by using H-1-NMR and GC analysis of (S)-O-acetyllactyl ester derivatives of 2-furylcarbinols. They were also correlated with the Literature values.
Palladium(0) nanoparticles supported on silica-coated cobalt ferrite: A highly active, magnetically isolable and reusable catalyst for hydrolytic dehydrogenation of ammonia borane
Akbayrak, Serdar; KAYA, MURAT; Volkan, Mürvet; Özkar, Saim (Elsevier BV, 2014-04-05)
Palladium(0) nanoparticles supported on silica-coated cobalt ferrite (Pd(0)/SiO2-CoFe2O4) were in situ generated during the hydrolysis of ammonia borane, isolated from the reaction solution by using a permanent magnet and characterized by ICP-OES, XRD, TEM, TEM-EDX, XPS and the N-2 adsorption-desorption techniques. All the results reveal that well dispersed palladium(0) nanoparticles were successfully supported on silica coated cobalt ferrite and the resulting Pd(0)/SiO2-CoFe2O4 are highly active, magnetica...
Palladium doped perovskite-based NO oxidation catalysts: The role of Pd and B-sites for NOx adsorption behavior via in-situ spectroscopy
Say, Zafer; Dogac, Merve; Vovk, Evgeny I.; Kalay, Yunus Eren; KIM, Chang Hwan; LI, Wei; Ozensoy, Emrah (Elsevier BV, 2014-07-01)
Perovskite-based materials (LaMnO3, Pd/LaMnO3, LaCoO3 and Pd/LaCoO3) were synthesized, characterized (via BET, XRD, Raman spectroscopy, XPS and TEM) and their NO (x= 1,2) adsorption characteristics were investigated (via in-situ FTIR and TPD) as a function of the nature of the B-site cation (i.e. Mn vs Co), Pd/PdO incorporation and H-2-pretreatment. NO adsorption on of LaMnO3 was found to be significantly higher than LaCoO3, in line with the higher SSA of LaMnO3. Incorporation of PdO nanoparticles with an a...
Viscoelastic properties of reactive and non-reactive styrene-maleic anhydride olefinic blends
Bayram, G; Yılmazer, Ülkü; Xanthos, M (2000-05-11)
Reactive blends of styrene-maleic anhydride (SMAH) with polyethylene/methyl acrylate/glycidyl methacrylate (PE-F) and non-reactive blends of SMAH with polyethylene/methyl acrylate (PE-NF) were produced and characterized in terms of morphology and viscoelastic properties in order to understand the reaction characteristics between anhydride/epoxy functional groups. Storage modulus, G', loss modulus, G " and complex viscosity, eta* of reactive blends at 25 % and 50 % PE-F were higher than those of non-reactive...
