(Springer, 2009)
The Schiff base compound, N-n-Decyl-2-oxo-5-nitro-1-benzylidene-methylamine, has been -synthesized and characterized by IR, electronic spectroscopy, and X-ray single-crystal determination. Molecular geometry from X-ray ...
Synthesis, spectroscopic, and molecular structure characterizations of some azo derivatives of 2-hydroxyacetophenone
(Elsevier, 2009)
Some novel azo compounds were prepared by the reaction of 2-hydroxyacetophenone with aniline and its substituted derivatives. The structures of synthesized azo compounds were determined by IR, UV-Vis, H-1 NMR and C-13 NMR ...
An intermediate structure trapped in solid-state tautomerization process of (E)-4-[(4-chlorophenylimino)methyl]benzene-1,2,3-triol
(Elsevier, 2008)
An intermediate structure between the benzenoid and cis-quinoid form of the title compound was trapped in solid-state tautomerization with the aid of O-H center dot center dot center dot O type intermolecular H-bonds leading ...
(E)-2-Methyl-6-[3-(trifluoromethyl)-phenyliminomethyl]phenol
(Blackwell Publishing, 2007)
The title compound, C15H12NOF3, adopts the phenol-imine tautomeric form. The molecule is approximately planar and intramolecular O-H center dot center dot center dot N hydrogen bonding generates an S(6) ring motif. C-H ...
Crystallographic and conformational analyses of zwitterionic form of (E)-2-methoxy-6-[(2-morpholinoethylimino)methyl]phenolate
