Abstract:
The title mol-ecule, C(13)H(11)Cl(2)N(3)O, is almost planar and adopts a trans conformation with respect to the -N=N- bond; the dihedral angle between the rings is 3.47 (2)°. The N-N bond lengths indicate the presence of single- and double-bond characters and hence the -N=N-NH- moiety. In the crystal, inversion dimers linked by pairs of N-H⋯Cl hydrogen bonds occur, and C-H⋯π and π-π stacking interactions are also observed.

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...
