The formation of the hydrogen bond stabilizes the chelated enol forms of β-diketones. Several experimental and theoretical data imply that some substituents in α- or β-positions significantly change the strength of ...

Intramolecular hydrogen bonding (IHB) and vibrational frequencies of 1,1,1-trifluoro-5,5-dimethyl-2,

4-hexanedione (TFDMHD) have been investigated by means of density functional theory (DFT) calculations, Atoms in ...

Conformational analysis, molecular structure, relative stability, and complete vibrational assignment of bis(2,2,6,6-tetramethylheptane-3,5-dionato)copper(II), Cu(tmhd)2, were investigated by density functional theory ...

Conformational stability, equilibrium constant between two stable cis-enol forms, and

intramolecular hydrogen bonding (IHB) of benzoylacetone (BA) and p-substituted benzoylacetone

(X-BA), where X=NO2, OCH3, ...

This paper presents a combined experimental and theoretical study on the CueO bond strength of

copper (II) a-methylacetylacetonate, Cu(3-Meacac)2, and copper (II) a-ethylacetylacetonate, Cu(3-

Etacac)2, ...

,-unsaturated--ketoamines are capable of forming an N-H…O asymmetric intramolecular hydrogen bond. The 4-amino-3-penten-2-one has an N-H…O intramolecular hydrogen bond. Furthermore this compound is capable of forming ...
