(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.

Structure and Nomenclature of Epoxides
Preparation of Epoxides
Epoxides result from alkene oxidation, which can be achieved by a) air, b) peroxy acids, c) hypochlorous acids, and d) halohydrin cyclization.
Epoxidation with Peroxy Acids
Epoxidation of alkenes via oxidation with peroxy acids involves the conversion of a carbon–carbon double bond to an epoxide using the oxidizing agent meta-chloroperoxybenzoic acid, commonly known as MCPBA. Since the O–O bond of peroxy acids is very weak, the addition of electrophilic oxygen of peroxy acids to...
Structure and Nomenclature of Ethers
Ethers are organic compounds with an ether functional group which is characterized by an oxygen atom connected to two — identical or different — alkyl, aryl, or vinyl groups. The C–O–C linkage in dimethyl ether — the simplest ether — has an approximately tetrahedral bond angle of 110.3 degrees. The oxygen atom is sp3- hybridized, with the C–O distance being about 140 pm.

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
