Özet

The aim of this study is to find out the molecular characteristic and structural parameters that govern the chemical behavior of a new (2-methoxyphenyl)oxalate compound and to compare predictions made from theory with experimental observations. The title compound, (2-methoxyphenyl)oxalate, (I), (C16H14O6), has been synthesized. The compound has been characterized by elemental analysis, IR, H-1 NMR, C-13 NMR spectroscopies and single crystal X-ray diffraction techniques. Optimized molecular structure, harmonic vibrational frequencies, H-1 and C-13 NMR chemical shifts have been investigated by B3LYP/6-31G(d,p) method using density functional theory (DFT). The calculated results show that the predicted geometry can well reproduce structural parameters. In addition, global chemical reactivity descriptors, molecular electrostatic potential map (MEP), frontier molecular orbitals (FMOs), Mulliken population method and natural population analysis (NPA) and thermodynamic properties have also been studied. The energetic behavior of title compound has been examined in solvent media using polarizable continuum model (PCM). (c) 2015 Elsevier B.V. All rights reserved,
