RISStructure and hydrogen bond strength of the enol form of Furoylacethylacetone
From the theoretical point of view, 32 enol forms for FAA can be drawn, which only four cisenol
conformers have the six-membered chelated ring of the intramolecular hydrogen
bonding (IHB). For comparison, the ...
Estimating the intramolecular hydrogen bonds strength in the O-H…O=C systems using experimental 1H NMR results and QTAIM calculations
and some selected calculated parameters due to intramolecular hydrogen bond strength. For this purpose the structure of a series of molecules containing the intramolecular O‒H···O=C hydrogen bond was studied by NMR spectroscopy, have been investigated...
Structure, vibrational analysisi and intramolecular hydrogen bond strength of some 4-amino-3-penten-2-one derivatives
useful complexes. To identify the structure and stability of these complexes, the structure and intramolecular hydrogen bond strength of these ligands should be investigated.
In this study, the molecular structure and vibrational spectra of 4...
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 ...
Intramolecular hydrogen bond strength of 3-methyl-4-amino-3-penten-2-one, an experimental approach
The intramolecular hydrogen bonding of 3-methyl-4-amino-3-penten-2-one, 3-MeAPO, has been investigated by experimental results, including NMR, IR, and UV spectra. According to 1H-NMR spectrum, the titled molecule is as a ...
