Heterogeneous catalytic efficiency of silica sulfuric acid toward the synthesis of substituted pyrimidin-2(1H)-one derivatives

Pyrimidine template is a highly privileged motif for the development of molecules of biological and pharmaceutical interest due to its prebiotic nature to life. This present study deals with the synthesis of pyrimidin- 2(1H)-one derivative from chalcones by the action of silica supported sulfuric acid (SSA) or conventional refluxed in concentrated hydrochloric acid. The chemical structures were confirmed by analytical...

Synthesis, characterization and corrosion inhibition of Co (II), Ni (II), Cu (II), and Zn (II) complexes derived from nicotinic acid hydrazide

Metal complexes formed by the reactions of nicotinic acid hydrazide (NAH) with copper (II), cobalt (II), nickel (II), and zinc (II) sulphate ions were prepared and characterized by their infrared, electronic, magnetic moment, elemental analysis, solubility, molar conductivity, and melting point as well as their corrosion inhibition properties using the weight loss method (WLM).   Key words: Ligand, Metal...

Gas chromatography-mass spectrometric analysis of methanolic leaf extract of Blighia sapida

Blighia sapida is a medicinal plant whose fruits and leaves possess therapeutic properties. This research is aimed at identifying the phytochemical constituents present in the leaves. The plant leaves were extracted with n- hexane and methanol. Phytochemical screening was carried out on both extracts while only the methanolic extract was subjected to gas chromatography-mass spectrometric (GC-MS) analysis. The...

Assessment of some metals in roadside dust from Damaturu, Yobe State, Nigeria

Roadside dust samples were collected from commercial and residential areas in Damaturu, Yobe State, Nigeria for the determination of Cr, Pb, Cu, Fe, Ni, Co, Mn, Cd, As and Zn. Sample preparation and digestion were carried out using standard procedures. The samples were determined using flame atomic absorption spectrophotometry after digestion with aqua regia. The levels of Cr, Pb, Cu, Fe, Ni, Co, Mn, Cd, As and Zn were...
