Abstract:
In the title compound, C(17)H(14)ClF(2)NO(2), the amino-acrylo-yloxy group makes dihedral angles of 47.55 (11)° with the 4-chloro-phenyl group and 8.74 (12)° with the difluoro-phenyl group; the dihedral angle between the rings is 52.32 (11)°. The structure of the title compound reveals a Z configuration with respect to the C=C double bond in the amino-acrylate fragment. A bifurcated intramolecular N-H⋯(O,F) hydrogen bond occurs. In the crystal, molecules are linked into chains by C-H⋯O hydrogen bonds.
