Conformational Analysis and Intramolecular Hydrogen Bonding in 4-Butylmino-3-Penten-2-One
According to our calculations, 2 stable conformers were obtained. They were
the same and the difference between them is the location of butyl group above or below the surface of
the molecule. The N…O distance ...
Normal coordinate analysis, hydrogen bonding, and conformation analysis of heptane-3,5-dione
Fourier transform Raman and infrared spectral measurements have been made for the heptane-3,5-
dione (HPD) and simultaneously compared with those of acetylacetone (AA) to give a clear understanding of substitution ...
CONFORMATIONAL ANALYSIS AND INTRAMOLECULAR HYDROGEN BONDING IN HEPTANE-3-AMINO-5-ONE
-Ketoamines are a class of chemical compounds which form an intramolecular hydrogen bonded system assisted by resonance [1]. These compounds are capable of forming complexes with metal ions [2]. To identify the structure ...
Structure, vibrational analysisi and intramolecular hydrogen bond strength of some 4-amino-3-penten-2-one derivatives
ABSTRACT: 4-Amino-3-penten-2-one (APO) is one of the interesting β-enaminones, involved in the N–H⋯O intramolecular hydrogen bond system assisted by resonance [1]. This special hydrogen bonding makes them to play the role ...
Structure and vibrational analysis of copper (II) heptane-3,5-dione
B-diketonates of different metals have been used in the preparation of some kinds of
catalysts [1,2]. In this study, the structure and vibrational spectra of copper (II) heptane-
3,5-dione, Cu(HPD)2, were ...
Conformation, molecular structure, and vibrational assignment of bis(3,5-heptanedionato)copper(II)
Density functional theory (DFT) and Atoms-in-Molecules (AIM) analyses as well as Fourier transform
Infrared, Raman, and UV spectra have been used to investigate the structure and vibrational spectra of
bis(3,5-hept ...
Conformations, molecular structure, and N–H⋯O hydrogen bond strength in 4-Alkylamino-3-penten-2-ones
4-Alkylamino-3-penten-2-ones (R-APO), R = H, CH3, C2H5, CH(CH3)2, and C(CH3)3, were synthesized by amination of acetylacetone and the products were characterized by 1HNMR spectroscopy. The intramolecular hydrogen bonding ...
