    Yüksek disordera sahip 2-fenil-4-[4-(1,4,7,10-tetraoksa-13-azasiklopentadesil)benziliden]-5-oksazolon Bileşiğinin Yapısal Karakterizasyonu ve DFT çalışmaları

    In this study, the crystal and molecular structure of the compound 2-phenyl-4-[4-(1,4,7,10-tetraoxa-13-azacyclopentadecyl)benzylidene]-5-oxazolone was determined by the single-crystal X-ray diffraction method. The molecular structure of the compound consists of a N-phenyl-(aza-15-crown-5) moiety connected to the oxazol-5-one ring. A phenyl group is also linked to the oxazol-5-one fragment. Crystal structure is stabilized by C–H···O type intermolecular hydrogen bonds, C–H···O type intramolecular interaction and pi···pi interactions. Theoretical studies such as molecular geometry, frontier molecular orbitals and molecular electrostatic potential were performed using the Density Functional Theory (DFT) method B3LYP/6-311G(d,p) basis set. Geometric parameters were compared with the experimental data and the compatibility was observed.</p

    A Theoretical Study of 2-hydroxyethyl Substituted NHC Precursors Containing ortho–, meta– and para– methylbenzyl: Global Reactivity Descriptors and Prediction of Biological Activities

    In this work, three 2-hydroxyethyl substituted N-heterocyclic carbene (NHC) precursors containing ortho–, meta– and para– methylbenzyl fragments are characterized theoretically. Theoretical calculations are performed to gain insight into these three molecules’ electronic properties (HOMO-LUMO energy, MEP and global reactivity descriptors) and biological behaviors. Also, atomic charges are calculated and molecular orbital analysis is performed. In order to investigate the stability of the molecules resulting from hyperconjugative interactions and charge delocalization, natural bond orbital (NBO) analysis is used. A predictive study for the biological activities is carried out using PASS (prediction of activity spectra for biologically active structures) online software. Biological activity predictions showed the substance P antagonist, analgesic and antiinflammatory activities of the compounds.</p
