(E)-4-Hy-droxy-N'-(3-hy-droxy-4-meth-oxy-benzyl-idene)benzohydrazide
Abstract:
The mol-ecule of the title benzohydrazide derivative, C(15)H(14)N(2)O(4), exists in a trans conformation with respect to the C=N double bond and is twisted, the dihedral angle between the two benzene rings being 24.17 (6)°. The meth-oxy group is almost co-planar with respect to the attached benzene ring [C(m)-O-C-C (m = meth-yl) = -1.45 (17)°]. In the crystal, the mol-ecules are linked by N-H⋯O and O-H⋯O hydrogen bonds into sheets parallel to the bc plane. These sheets are further connected into a three-dimensional network by weak C-H⋯O and C-H⋯π inter-actions.

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...
