(E)-ethyl 4-chloro-3-[2-(2-fluorophenyl)-hydrazono]butanoate
(Int Union Crystallography, 2005)
The title compound, C12H12ClFN2O3, adopts a keto-hydrazo tautomeric form stabilized by an intramolecular N-H (. . .) O hydrogen bond. The whole molecule is roughly planar, the largest deviation from the mean plane being ...
Ethyl 4-chloro-3-oxo-2-(phenylhydrazono)butyrate
(Int Union Crystallography, 2005)
The title compound, C12H13ClN2O3, adopts a keto-hydrazo tautomeric form stabilized by an intramolecular N-(HO)-O-... hydrogen bond. The configuration around the C = N bond is trans. The dihedral angle between the aromatic ...
