Synthesis and structural properties of $N$-3,4-(dichlorophenyl)-3-oxo-3- phenyl-2-(phenylcarbonyl)propanamide and its Cu(II) complex

Abstract

A new N-carboxamide compound (3) was synthesized by the reaction of dibenzoylaceticacid-N-carboxyethylamide (1) and 3,4-dichloroaniline (2). The N-(3,4-dichlorophenyl)-3-oxo-3-phenyl-2-(phenylcarbonyl) propanamide (3) subsequently reacted with Cu salt to produce its Cu(II) complex compound (4). The compounds were characterized by analytical and spectral methods. In addition, X-ray diffraction was performed to characterize and obtain detailed information about the structure of 3. The fully optimized geometries of compounds 3 and 4 were calculated at different basis sets by using the Gaussian09 (G09) software to investigate their 3D geometries and electronic structures. Comparisons between the calculated and experimental data including molecular structures, fundamental vibrational modes, and electronic properties were made. The comparisons showed that the theoretical data were compatible with the corresponding experimental values of compounds 3 and 4.

Synthesis, Characterization, Photoluminescence Properties and Antiproliferative Activity of New Pd(II), Ni(II) and Cu(II) Mixed Complexes Bearing Schiff Base Ligand and 1,10‐phenanthroline

“…Each compound‘s spectra are fairly similar to one another, with three primary absorption bands. Examining the absorption bands of Cu(II), Ni(II) and Pd(II) metal complexes reveals that π‐π* transitions, n‐π* transitions, and charge transfer transitions occur between 270 and 285 nm, 295 to 345 nm and 415 to 550 nm, respectively [52–54] …”

“…Examining the absorption bands of Cu(II), Ni(II) and Pd(II) metal complexes reveals that π-π* transitions, n-π* transitions, and charge transfer transitions occur between 270 and 285 nm, 295 to 345 nm and 415 to 550 nm, respectively. [52][53][54] The mixed ligand Pd(II) complex is diamagnetic and has a square planar geometry. [55] Magnetic susceptibility values of mixed ligand mononuclear Cu(II) complexes are in the range of 1.72-1.80 B.M.…”

Synthesis of new thiazine and thiazole derivatives via cyclization reactions; investigating their electronic properties and determination of antioxidant properties

“…In the IR spectrum of compound 1 , absorption peaks for NH appeared at 3235 and 3143 cm −1 . The absorption peak of the C=O group belonging to the benzoyl group was observed at 1647 cm −1 [24]. If the 1 H NMR spectrum of compound 1 is examined, the peaks observed at 10.29 and 9.36 ppm can be interpreted as the peaks belonging to the NH group.…”

New Carboxamid ligand and its metal complexes containing sulfonamide group: Synthesis, Characterization, DNA cleavage and antimicrobial activity

“…The coordination of the amide-nitrogen to metal ions was indicated by the shifting of the v(N-H) bands to higher frequencies. The stretching vibration band of the C=O↔C-OH enolic group (1668 cm -1 ) cannot be observed in the spectra of the metal complexes due to deprotonation of the ligand (HL) when it is bonded to the metal atom (Demir et al, 2016;Sarioglu et al, 2016). The FT-IR spectrum confirms complexation reaction with the shift of the N-H band and disappearance of the C=O bands.…”

“…The FT-IR spectrum confirms complexation reaction with the shift of the N-H band and disappearance of the C=O bands. The spectra of complexes showed also new bands at 409-493 and 527-543 cm -1 attributed to (M-O) and (M-N) vibration, respectively (Sönmez, 2001;Sarioglu et al, 2016;Sönmez et al, 2018). The carbonyl stretching mode is simultaneously influenced by the conjugation of C=O with amide nitrogen and the intermolecular hydrogen bonding.…”
