The configuration about each C=N bond in the title compound, C(22)H(20)N(4)O(3)S, is E. While to a first approximation the phenyl-hydrazin-1-yl-idene and benzohydrazide residues are coplanar, in part due to the presence of an intra-molecular N-H⋯N hydrogen bond, significant twists are evident in the orientations of the hydrazine [N-N-C-C torsion angle = -170.74 (11)°] and benzoyl benzene [N-C-C...
Heterocyclic chemistry has fascinated the researchers owing to its wide range of applications in various chemical fields. With this perspective, herein we present an environmentally benign procedure for synthesis pyrazole and derivatives through multicomponent reaction by using SPVA as a heterogeneous acid catalyst. The protocol catalyst includes functionalization polyvinyl alcohol sulfonic gro...
The effect of ethanol leaf extract Alchornea cordifolia on some biochemical parameters in phenyl hydrazine-induced anaemic Wistar rats was studied. A total thirty-six (36) weighing 95-200 g were selected for this study and randomly divided into six groups animals per group. Group (normal control), group B (negative or anaemic) control, C (standard), D, E F (treated groups). Animals B, C, induce...
Hydrazine is rarely found as an intermediate in microbial nitrogen conversions. In this study the conversion of hydrazine by the anaerobic ammonium oxidation (Anammox) culture, in which hydrazine has been proposed as an intermediate, was investigated. This study demonstrated the biological nature of hydrazine conversion by the Anammox culture. In batch cultures with hydrazine it was observed th...
In this study, we aimed to develop new biologically active compounds with antibacterial properties. 4-amino-5-methyl-2H-1,2,4-triazol-3(4H)-one (1) was converted the corresponding Schiff bases (2) reaction a 4-anis aldehyde. Acetic acid ethyl esters containing [1,2,4] triazole ring (3) were synthesized by condensation of bromoacetate in basic media. The hydrazine hydrate led formation hydrazide...
Ni(II), Cu(II), and Zn(II) complexes of the tridentate heterocyclic ligand, 2-(phenyl(pyridin-2-yl)methylene)hydrazine-1-carbothioamide (HL) have been synthesized characterized by various spectroscopic techniques elemental analyses. Infrared spectroscopy shows that ligand coordinates to metal ions through azomethine pyridine nitrogen atoms as well sulfur atom thioamide group form a chelate syst...
In this paper, new (2E, 2'E)-3, 3'-(((3- hydroxypropane-1, 2-diyl) bis (oxy)) bis (2, 1-phenylene)) bis (1-phenylprop-2-en-1-one) (2a) was prepared in good yield by condensation reaction of acetophenone with bisaldehyde (1a) in ethanolic NaOH solutions at room temperature. The (2E, 2'E)-3, 3'-(((3- hydroxypropane-1, 2-diyl) bis (oxy)) bis (2, 1-phenylene)) bis (1-phenylprop-2-en-1-one) (2a) was...
Administration of hydrazine to fasted rats results in a state of hypoglycemia which slowly abates over a period of several hours. Hydrazine also abolishes the increase in blood glucose normally seen after administration of hydrocortisone to fasted rats. Comparison of the concentrations of hepatic metabolites of rats treated with hydrazine with those of control rats reveals that hydrazine causes...
