The title compound, C22H19NO2, is an imino-ketone Schiff base. The configuration about the azomethine bond is E. The aromatic rings of the 1,2-di-phenyl-ethanone moiety are inclined to each other by 80.43 (7)°. The 4-eth-oxy-phenyl ring is inclined to the phenyl-ethanone ring by 81.91 (7)° and to the phenyl ring to which it is trans by 68.56 (7)°. In the crystal, four symmetry-related mol-ecules are linked by C-H⋯O hydrogen bonds to form square-like units with an R 3 4(36) ring motif, which are linked through bifurcated C-H⋯O hydrogen bonds to form sheets parallel to the (101) plane.

Structure and Nomenclature of Epoxides
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...

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...
E2 Reaction: Stereochemistry and Regiochemistry
When a substrate with two different β hydrogens undergoes an E2 elimination, the presence of a strong base can yield two regioisomeric alkenes. The more-substituted alkene is the major product and...
