Nitrate d’hydrazine

Thermal decomposition of symmetrical hydrazines (212a-d) according to equation 30 resulted in excellent yields of hindered esters (231a-d). The hydrazines leading to the esters were generated as intermediates by the oxidation of Af-alkoxyamides using ceric ammonium nitrate or Ni02.H20 (Scheme 31).

Olander, "Spontaneous Explosion of a Normally Stable Complex Salt , JChemEduc 32, 24(1955) [The salt which spontaneously exploded was pure Trihydrazinenickel(II) nitrate prepd by adding an ethanolic soln of nickelous nitrate, slowly and with agitation, to a 40% ethanolic soln of hydrazine hydrate. The pptd fine pink pdr was separated, washed with ethanol and then dried for 16 hrs in... 

Although hydrazine hydrate in ethanol is effective in achieving denitration of carbohydrate nitrates,243,244 the reagent showed little selectivity in its reactions244 with the 2,3-dinitrates of methyl 4,6-O-ben-zylidene-a- and methyl 4,6-0-ethylidene-a- and -/3-D-glucopyranoside. 

Urbanski (Ref 53) also studied the effect of addition of such non-solvent liqs as H20, C7H14, CHO3, iso-CsHuOH, glycerol, castor oil, o-and p-nitrotoluene, PhNH2, and glycerol triacetate, on the deton rate of RDX. He also found that as liq content increased, the D vs %liq curve passes thru a max. Kegler (Ref 65) investigated the effect of the addition of w and aq solns of amm nitrate or hydroxide, hydrazine or nitric acid on the D of RDX. Unfortunately his data are unavailable to us...
