In this study, a series of N-pyridin-3-yl substituted [phenylsulphonamido] acetamide has been synthesized. The reaction of phenylsulphonyl chloride with various amino acids in basic medium yielded phenylsulphonamido alkanoic acid which, on chlorination with thionyl chloride, gave acid chloride derivatives of phenylsulphonamido alkanoic… Continue Reading
The rate of reaction defines as the concentration of reactant or product, consumed or produced within a given time frame. Changing one of the variables could lead to a differing rates of reaction speeds. … Continue Reading
This manuscript contains an insight into the mechanisms of inorganic carbene chemistry; synthesis of imidazolium salts from its precursors to using computational chemistry to calculate their quantum mechanical properties. As well as an attempt to deprotonate the iPr imidazolium salt and coordinating the carbene to a standard but labile Ni(0)… Continue Reading

Chelates of 2-bromovaleric acid hydrazide (BVH) and acetone2- bromovaleric acid hydrazone (ABVH) with MS04 (where M is Ni, Cu, Co, Mn, Zn, V02+) were synthesized in water-methanol medium. They were characterized by infrared and electronic spectral studies, solubility, elemental analysis, conductivity and antimicrobial screemng. Electronic… Continue Reading
A biofuel is a fuel that produced through contemporary biological processes such as agriculture and anaerobic digestion, rather than a fuel produced by geological processes. It can be derived directly from plants or indirectly from agriculture or industrial waste. Bioethanol is an alcohol made by fermentation, it is produced from sugar or… Continue Reading
Phytochemical screening of methanol extract of leaves of Albizia Amara revealed the presence of secondary metabolites: saponins, alkaloids, tannins, glycosides and flavonoids. Powdered shade- dried leaves (1kg) of A. amara. were extracted with 95% ethanol at room temperature for 48 hours, The crude extract was suspended in water and… Continue Reading
This study was aimed to extract the fixed oil of Apium graveolens through the process of maceration with normal hexane. The oil was analyzed by gas chromatography-mass spectrometry. The antimicrobial activity was also estimated. The GC-MS analysis of the studied oil showed the presence of 45 constituents. Major components are: i)… Continue Reading
Assessment of the effects of carbonated drinks on the teeth have been carried out. Five white shelled hard-boiled eggs were placed in clear cups and labelled ( Soda Drink, Diet Coke, Coke, Tap Water and Vinegar) , with the respective selected liquid poured into the cups and ensured the liquid covers the eggs placed in the cups. The eggs… Continue Reading
3,5-Bis[(2-hydroxy-benzylidene)-amino]-benzoic acid (H2B) and its cobalt(II) and nickel(II) complexes were synthesized and characterized via: electronic, IR, 1 H NMR and 13C NMR. Job’s continuous variation method was used to determine the mole ratio for both metal complexes. Solvent extraction studies were carried out on H2B in 5% DMF… Continue Reading
