Chemistry of Heterocyclic Compounds Aims and scope

Abstract

Enaminofurazans were obtained by reaction of vinyl ethers with 3,4-diaminofurazan. It was established by IR and PMR spectroscopy that enaminofurazans exist in the form of a chelate complex. The structure of the chelate complex is discussed. Enehydrazides were obtained by reaction with furazan-3,4-dicarboxylic acid dihydrazide. When there is a cyano group in the ether molecule, the reaction does not stop with the formation of the enehydrazide but continues with its cyclization to give a pyrazole ring.
