Abstract:
The title compound, C(16)H(17)ClF(3)NO(2), was synthesized from 3-[(E)-2-chloro-3,3,3-trifluoro-prop-1-en-yl]-2,2-dimethyl-cyclo-propane-carboxylic acid and 3-methoxy-benzenamine. The propenyl and carboxamide substituents lie on the same side of the cyclo-propane ring plane, with the two methyl substituents on either side of the plane. The benzene ring makes a dihedral angle of 76.4 (3)° with the plane of the cyclo-propane ring. The crystal structure involves intermolecular N-H⋯O hydrogen bonds.

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.
Classification of Ethers
Based on their attached substituent groups, ethers can be classified into two...
Nomenclature of Carboxylic Acid Derivatives: Amides and Nitriles
The IUPAC and common names of amides are derived from the parent carboxylic acid, by replacing the suffix “oic acid” and “ic acid,” respectively, with “amide.” In the following example, the IUPAC name ethanamide is derived from ethanoic acid, and the common name, acetamide, is obtained from acetic acid.
Alkyl Halides
Alkyl halides are halogen-substituted alkanes wherein one or more hydrogen atoms of an alkane is replaced by a halogen atom such as fluorine, chlorine, bromine, or iodine. The carbon atom in an alkyl halide is bonded to the halogen atom, which is sp3-hybridized and exhibits a tetrahedral shape.
Unlike alkyl halides, compounds in which a halogen atom is bonded to an sp2 -hybridized carbon atom of a carbon-carbon double bond (C=C) are called vinyl halides. Whereas aryl...
