(E)-1-(Pyridin-2-yl)ethanone O-acryloyloxime
نویسندگان
چکیده
The title compound, C(10)H(10)N(2)O(2), was synthesized by the reaction of the oxime of 2-acetyl-pyridine and 3-bromo-propanoyl chloride in the presence of triethyl-amine. The mol-ecule adopts a nearly planar chain-extended conformation with the oxime group in a trans and the acryloyl group in an s-cis conformation. This conformation is stabilized by an intra-molecular C-H⋯N hydrogen bond. The screw-related mol-ecules are linked into C(9) chains by C-H⋯O hydrogen bonds.
