Structures and Chemistry of Amino and Nitro Furazans

摘要

The furazan ring has become the subject of significant investigation in recent years due to its potential as a ballistic modifier and fuel in energetic materials formulations. This thesis is a study of compounds with amino and nitro substitution on one or two furazan rings. Dinitrogen groups are the bridge for the two-ring systems. The synthesis and characterization of these compounds is presented. Dinitrohydrazofurazan is a new compound. Flash-pyrolysis by T-Jump/FTIR spectroscopy was performed on these compounds to determine the pyrolysis products. X-ray crystallography was performed on five compounds and structural details are compared. Density functional theory calculations were performed on all of the compounds to compare the heats of formation and establish the atom motions that most dominate the IR absorptions.
