Phenacylmalononitrile 1 reacts with dimethylformamide dimethyl acetal to yield an enaminone which could be readily converted into a pyrrole or an aminopyridazine by treating with ammonium acetate and hydrazine hydrate, respectively. Compound 1 reacted with hydrazine hydrate in ethanol at room temperature to yield the dihydropyridazine 9 as a single product. In refluxing ethanol this product fur...

The title compound, 3C(14)H(12)N(2)O(2)·C(3)H(7)NO, was synthesized by reaction of benzoyl chloride with hydrazine hydrate under microwave irradition. The asymmetric unit comprises three 1,2-dibenzoyl-hydrazine mol-ecules and one dimethyl-formamide mol-ecule. The 1,2-dibenzoyl-hydrazine mol-ecules are linked by pairs of N-H⋯O hydrogen bonds into chains propagating along [010].

Two new salts of the cation [CuI(dmp)2]+ (dmp is 2,9-dimethyl-1,10-phenanthroline, C14H12N2), namely bis[bis(2,9-dimethyl-1,10-phenanthroline-kappa2N,N')copper(I)] bis(hexafluorophosphate) hemi[bis(4-pyridylmethylidene)hydrazine] acetonitrile solvate, [Cu(C14H12N2)2]2(PF6)2.0.5C12H10N4.C2H3N or [Cu(dmp)2]2(PF6)2.0.5(bpmh).CH3CN [bpmh is bis(4-pyridylmethylidene)hydrazine, C12H10N4], (I), and bi...

The mol-ecule of the title compound, C(16)H(16)N(2), is centrosymmetric and the dihedral angle between the benzene ring and the dimethyl-hydrazine mean plane is 16.11 (15)°.

QSAR/QSTR modelling constitutes an attractive approach to preliminary assessment of the impact on environmental health by a primary pollutant and the suite of transformation products that may be persistent in and toxic to the environment. The present paper studies the impact on environmental health by residuals of the rocket fuel 1,1-dimethyl hydrazine (heptyl) and its transformation products. ...

background: 1, 2-dimethylhydrazine (dmh) enhances lipid peroxidation rate by tumor mitochondria than normal tissue counterpart and causes many disorders in antioxidant system in liver. it also increases the level of enzymes that metabolize toxin in liver and colon. the aim of this study was to evaluate the alteration of liver and its enzymes after dmh injection and evaluate protective effect of...

In the title compound, C(26)H(19)N(3)O, the dimethyl-ene hydrazine (-C=N-N=C-) unit is approximately planar, the torsion angle around the N-N bond being 162.2 (6)°. The phenyl and benzoyl-phenyl rings at one end of the hydrazine unit are aligned at angles of 9.5 (5) and 88.5 (4)°, respectively, with respect to the hydrazine unit, whereas the benzene ring at the other end is twisted by an angle ...
