Abstract:
In the title compound, C16H14O4, the benzene rings are inclined to one another by 4.91 (7)°. The conformation about the C=O and C=C bonds is trans and cis, respectively. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, forming inversion dimers with an R 2 (2)(14) ring motif. The dimers are linked via O-H⋯O and C-H⋯O hydrogen bonds, forming undulating two-dimensional networks lying parallel to (10-1). These networks are linked by further C-H⋯O hydrogen bonds, forming a three-dimensional structure.

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...
