Abstract:
The mol-ecule of the title compound, C16H16N2O4, adopts an E conformation about the azomethine C=N double bond. The dihedral angle formed by the benzene rings is 18.88 (9)°. The mol-ecular conformation is stabilized by an intra-molecular O-H⋯N hydrogen bond, which forms an S(6) ring. In the crystal, the mol-ecules are linked into chains parallel to [001] by N-H⋯O hydrogen bonds. The chains are further connected into a three-dimensional network by π-π stacking inter-actions with centroid-centroid distances of 3.6538 (10) and 3.8995 (11) Å.

Structure and Nomenclature of Epoxides
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...
