title: (E)-(2,4-Dichloro-phen-yl)[2-hydr-oxy-6-(methoxy-imino)cyclo-hex-1-en-yl]methanone.
abstract: The title compound, C(14)H(13)Cl(2)NO(3), was obtained as the product of an attempted synthesis of herbicidally active compounds containing oxime ether and cyclo-hexenone groups. In the crystal structure, the mol-ecule adopts an endocyclic enol tautomeric form and the cyclo-hexene ring adopts a distorted envelope form. The oxime ether group has an E configuration, with the meth-oxy group anti to the ortho-chloro substitutent. Intra-molecular O-H⋯O and inter-molecular C-H⋯O hydrogen bonds are found in the crystal structure.
