Facile Preparation of (2Z,4E)-Dienamides by the Olefination of Electron-deficient Alkenes with Allyl Acetate
Published on: June 21, 2017
(E)-1-(4-Fluoro-phen-yl)-3-(4-methyl-phen-yl)prop-2-en-1-one
Abstract:
The title compound, C(16)H(13)FO, adopts an E configuration with respect to the C=C bond of the propenone unit. The dihedral angle between the two benzene rings is 47.0 (5)°. Intra-molecular C-H⋯O hydrogen bonds generate an S(5) ring motif. In the crystal structure, mol-ecules are packed into columns along the c axis and the structure is stabilized by weak intra-molecular C-H⋯O hydrogen bonds and inter-molecular C-H⋯π inter-actions involving both aromatic rings.

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.

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.
