Urease enzyme was immobilized in photographic gelatin by chemical cross-linking using formaldehyde, glutaraldehyde and chromium (III) acetate. The effects of enzyme and cross-linker concentrations, temperature, incubation time and pH on urea hydrolysis were investigated. Effect of reuse on the activity of immobilized enzyme was also studied. Glutaraldehyde (0.004 M) was the most suitable cross-linker; relative activities within 2.5 months after 24 reuses were stable (about 78%).
Studies on the reaction of acyl phosphonates with aldehydes in the presence of proline
Yalçınkaya, Hatice; Demir, Ayhan Sıtkı; Department of Chemistry (2009)
Acyl phosphonates are interesting precursors for the synthesis of biologically active compounds. In the first part, the acyl phosphonates are synthesized starting from the corresponding acyl chloride. The acyl chlorides are converted into acyl phosphonates by using trialkylphosphites. The reaction of acyl phosphonates with aldehydes in the presence of proline furnished not the suggested aldol products via proline catalyzed aldol reaction but bicyclic products via one pot tricomponent 1,3-dipolar cycloadditi...

Studies On Dodecaborate Dianion And Carborate Anion Amination And Their Use In Stabilization Of Aryldiazonium Cations
Ünver, Ozan; Akdağ, Akın; Department of Chemistry (2022-2)
Boron is one of the most interesting elements in the periodic table. Boron chemistry is not ordinary due to the bonding. The bonding in boron related compounds is classified as non-classical bonds. Due to the bonding nature of boron, boron clusters have interesting properties, i.e. weakly coordinating ability. With this in mind, in this thesis, dodecaborate dianion and carborate anion were synthesized. The synthesized boron cages were derivatized and were subjected to amination reactions with two different ...
