Dinuclear complexes of copper, silver and gold bridged by phosphoruspyridyl and phosphorusnaphthyridyl ligands.
(1995)Chapter 1 setves as an introduction to the synthesis and characterisation of copper(!), silver(!) and gold(!) complexes of the 2,6-bis( diphenylphosphino )pyridine { (Ph2P)2py}, phenylbis(2- pyridyl)phosphine {PhP(py)2 ... -
Isolation and characterisation of bioactive compounds from antidesma venosum E.Mey. ex Tul. and euphorbia cooperi N.E.Br. ex A.Berger.
(2018)The need for the discovery of new pharmacologically active compounds is a global priority as new diseases and drug resistance mechanisms are emerging and spreading throughout the world. In the past natural products have ... -
Base-Free Suzuki acylation reactions of sodium (aryl trihydroxyborate) salts: a novel synthesis of substituted aryl ketones.
(2018)Asymmetric biaryl ketones are important building block in organic chemistry since they occur in large number of biological active compounds, natural product, cosmetics as well as in organic synthesis. The aim of this project ... -
Synthesis, characterization and evaluation of ionic liquids and polymeric ionic liquids/functionalized multiwalled carbon nanotubes for Cr(VI) adsorption.
(2019)In this study, a series of imidazolium and pyridinium-based ionic liquids (ILs), polymeric ionic liquids (PILs), and their carbon nanotubes-functionalized composites were synthesized, characterized and applied as potential ...
