Gollu, Mehmet
Demir, Ayhan Sıtkı
The self-condensation reaction of benzoyl dialkyl phosphonates was developed using cyanide ion as catalyst, affording versatile tertiary O-protected alpha-hydroxy phosphonates in moderate yield.


Thermal catalytic hydrosilylation of conjugated dienes with triethylsilane in the presence of tricarbonyl(o-xylene)metal (metal = Cr, Mo, W) complexes
Kayran, C; Rouzi, P (Walter de Gruyter GmbH, 2001-11-01)
The thermal catalytic hydrosilylation of 1,3-butadiene (1), trans-2-methyl-1, 3-pentadiene (2), 2,3-dimethyl-1,3-butadiene (3), and isoprene (4), with triethylsilane were studied in the presence of M(CO)(3) (o-xylene) (M = Cr, Mo, W) complexes in polar and nonpolar solvents such as tetrahydrofuran, hexane and toluene. Mo(CO)(3) (o-xylene) was found to be the only active catalyst for the hydrosilylation of 3 with triethylsilane, which gave 1-triethylsilyl-2,3-dimethyl-2-butene (3a), as hydrosilylated product...
Aryl butenoic acid derivatives as a new class of histone deacetylase inhibitors: synthesis, in vitro evaluation, and molecular docking studies
Esiyok, Peruze Ayhan; Seven, Ozlem; Eymur, Guluzar; Tatar, Gamze Bora; DAYANGAÇ ERDEN, DİDEM; YELEKÇİ, Kemal; YURTER, HAYAT; Demir, Ayhan Sıtkı (The Scientific and Technological Research Council of Turkey, 2014-01-01)
New aryl butenoic acid derivatives have been synthesized by combining hydroxy- or methoxy-substituted phenyl rings as the capping group, with a double bond in the short linker as well as metal binding groups, enoic ester, and salts bearing either methyl or morpholine. These compounds have been shown to possess promising histone deacetylase inhibition activities via in vitro fluorometric assay and molecular docking studies.
One-step synthesis of hierarchical [B]-ZSM-5 using cetyltrimethylammonium bromide as mesoporogen
Yalcin, Busra Karakaya; İpek Torun, Bahar (The Scientific and Technological Research Council of Turkey, 2020-01-01)
One-step facile synthesis of boron containing ZSM-5 microspheres is developed using 1,6-diaminohexane as the structure-directing agent and cetyltrimethylammonium bromide as the mesoporogen. High boron incorporation up to Si/B ratio of 38 is achieved and evidenced by the stretching vibrations of B-O-Si at 667 cm(-1) and 917 cm(-1) using Fourier-transform infrared spectra. The morphology of the crystals resembles berry-like spheres with sizes approximately 15 mu m, which is composed of aggregated nanocrystals...
Atom transfer rearrangement radical polymerization of diammine-bis(2,4,6-trihalophenolato)copper(II) complexes in the solid state
Goekagac, Guelsuen; Sonsuz, Muammer; Sen, Fatih; Kisakuerek, Duygu (Walter de Gruyter GmbH, 2006-10-01)
The synthesis of the poly(dichloro- or dibromophenylene oxide)s was achieved by the thermal decomposition of diammine-bis(2,4,6-trihalophenolato)copper(II) complexes in the solid state by atom transfer rearrangement radical polymerization. The thermal decomposition was performed either at different temperature ranges, 110-250 degrees C, for 3 h, or at the maximum conversion temperature for different time intervals, 3-48 h. Maximum yields of polymers were obtained at 190 degrees C and 3 h. The polymers were ...

The catalytic characteristics of massive and loaded sulfonic resins in the synthesis of ethyl tert-butyl ether at atmospheric and increased pressures have been compared. It has been established that massive sulfonic resins are more active than loaded resins at atmospheric pressure. At higher pressures, on the other hand, the activity and selectivity of catalysts are greater the lower the content of polymer as a result of the increased effectiveness of the acid centers.
