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 redu...

The complete mol-ecule of the title compound, C(16)H(12)N(2)O(4), is generated by the application of a centre of inversion. The (1,3-benzodioxol-5-yl)methyl-idene fused-ring system is approximately planar (r.m.s. deviation = 0.020 Å) and is essentially coplanar with the central hydrazine group [dihedral angle = 5.08 (9)°]. Weak π-π inter-molecular inter-actions are observed [centroid-centroid d...

ABSTRACT Introduction Hydrazines are highly toxic inorganic liquids that used as propellants in military and aviation industries, such the U.S. Air Force F-16 Emergency Power Unit SpaceX SuperDraco Rockets. The most commonly derivatives include hydrazine, monomethylhydrazine, 1,1-dimethylhydrazine (unsymmetrical dimethylhydrazine). Industrial workers close contact with hydrazines during routine...

Within recent years hydrazine and the methyl substituted hydrazines have come into considerable use as rocket fuels. As a result of this increased production of hydrazines, the possibility of accidental human exposure is of considerable interest. Obvious concern results from the fact that hydrazine had been used as an experimental means of producing fatty liver in experimental animals for many ...

Treatment of the monomeric trialkylelement compounds Al(CMe3)3, Ga(CMe3)3, and In(CMe3)3 with different hydrazines H2N–N(H)R (R = Me, CMe3, C6H5) yielded the corresponding adducts (Me3C)3E ← NH2–N(H)R, 1 to 9, in almost quantitative yields. All products were characterized by crystal structure determinations and shown to have the NH2 group of the hydrazine ligands attached to the central Group 1...

Oxazepam (4a) has been used as overall starting material in the synthesis of novel 2-substituted 1,4-benzodiazepines.By reacting Oxazepam 4a with commercially available hydrazines, hydrazides, semicarbazide, aminoguanidine and N,N-dimethylamino aniline in ethanol under acetic conditions, a series of diazenyl-1,4-benzodiazepines 5aâ5i and 2-amino-1,4-benzodiazepine 5k were obtained in good yield...
