The instant invention provides processes for a chemo selective reduction of a nitro group within a compound in the presence of other groups which can also be reduced. This aspect of the present invention provides an ammonia borane (AB) initiated chemoselective reduction process of a nitro group contained within a compound in the presence of a copper (Cu) nanoparticle based catalyst. The invention is also directed to Copper (Cu) nanoparticle (NP) based catalysts, selected from Cu/WO

synthesis, structures and the physical properties of a homologous series of copperalkylphosphonates. Cu(O3PCH2CH3)·H2O (CuPC2) and Cu(O3PCH2CH2CH3)·H2O (CuPC3) are both monoclinic with the same space group P21/a. Hydrothermal synthesis gave blue plate-like crystals allowing singlecrystal resolution. The synthesis in solution of the homologous series, from phosphonic acids possessing different alkyl chain
The chemical synthesis of cytidine-5'-alkyl- and cytidine-5'-alkyl (acyl)deoxyglycerophosphonophosphates is reported. The compounds obtained represent a novel class of cytostatically active agents based on phospholipids, which inhibit the growth of various tumor cell lines in vitro. They are phosphono analogs of the cytidine-5'-diphosphate-diacylglycerol (CDP-DAG) possessing a structurally modified lipid
