experimental part, p. 255 - 262 (2012/07/03)
A catalytic method for the synthesis of a class of hydrazine derivatives is reported. The described method provides convenient access to compounds which are anticipated to show biological activities. The salient features of this process include operational simplicity, good yields, and easily accessible starting materials.

3-Phenacyl- and 3-alkoxycarbonyl-1-methylimidazolium bromides react with two molecules of diethyl azodicarboxylate in the presence of triethylamine with the extrusion of the imidazole ring and the concomitant migration of an ethoxycarbonyl group to yield 3-substituted tetraethyl 1,2,4,5-tetra-azapent-3-ene-1,1,2,5-tetracarboxylates (5), the structure of which has been confirmed by X-ray crystallography, (6), and (7).
