3,4-Diaminofurazan

Description

3,4-Diaminofurazan (DAF) is a simple furanocyclic compound. Since DAF molecule has two highly reactive neighbouring amino groups, it is considered to be the basic structure for the preparation of other complex energetic compounds by oxidation, acylation and azide reactions. Energetic compounds based on DAF include: aminonitrofurazan (ANF), 3,4-dinitrofurazan (DNF), 4,4-diamino-3,3-diazofurazan (DAAF) and 4,4-diamino-3,3-diazofurazan (DAAzF).

The Uses of 3,4-Diaminofurazan

3,4-Diaminofurazan is a building block used to prepare magnesium and zinc alkynylated salicylaldehyde-diamine Schiff base complexes. 3,4-Diaminofurazan is also used to prepare aryl(hydroxy)oxadiazolopyrazines via oxidation of acetophenones followed by heterocyclization with antibacterial-activities.
