(E)-1-[4-(Hex-yloxy)phen-yl]-3-(3-hy-droxy-phen-yl)prop-2-en-1-one
Abstract:
There are two mol-ecules in the asymmetric unit of the title compound, C(21)H(24)O(3), in which the dihedral angles between the aromatic rings are 6.4 (1) and 7.0 (1)°. The enone moiety of both mol-ecules adopts an s-cis configuration. In the crystal, inter-molecular O-H⋯O and C-H⋯O inter-actions to the same acceptor O atom generate R(2) (1)(6) ring motifs and further C-H⋯O inter-actions generate R(2) (2)(8) ring motifs. Topologically, the R(2) (1)(6) and R(2) (2)(8) ring motifs are arranged alternately, forming [001] chains of mol-ecules. The crystal structure is further stabilized by C-H⋯π inter-actions.

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.
As with other organic compounds, alcohols and phenols...
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...
