Synthesis and Properties of Higher Nuclearity Polyazanes

Polyazanes (i.e., higher nuclearity homologues of hydrazines) with increasing numbers bound nitrogen atoms (from 3 to 5), including the first pentazane ever described, were prepared by addition lower-order polyazanes diazo reagents. A structure was obtained. It shown that polynitrogen chains adopt a helical conformation. DFT modeling shows arrangement persists in solution. Although are all reducing agents, they become less so as number nitrogens increases.
