  • Synthesis, Characterization and catalytic activity of Palladium-Based Metallodendrimer with Triazine

    Synthesis, Characterization and catalytic activity of Palladium-Based Metallodendrimer with Triazine Md. Sayedul Islam1* and Md. Wahab Khan2 1,2Department of Chemistry, Faculty of Engineering, Bangladesh University of Engineering and Technology (BUET), Dhaka-1000, Bangladesh A novel Pd-based metallodendrimer has been directly prepared by the reaction of substituted triazine with substituted benzoyl chloride in good yields using (Ph3P)2PdCl2 and DMF at 70 oC. This procedure avoids the use of high temperature and severe reaction conditions. The surface morphology like as entangled nanofibers from…

  • Synthesis of Bicyclic Adduct through Regioselective Baeyer-Villager oxidation

    Synthesis of Bicyclic Adduct through Regioselective Baeyer-Villager oxidation Bello Y. Makama* and Wahidullah Azizi Division of Mathematics, Sciences & Technology, American University of Afghanistan, Darul-Amman, Kabul, Afghanistan Baeyer-Villager oxidation reaction has become accepted as a right approach in the ring expansions for the preparation of both bicyclic and tricyclic lacotnes; however, successful application of the regioselective Bayer-Villager oxidation protocol to the synthesis of particularly congested scaffolds remains distinctly tricky. Herein the Baeyer–Villiger oxidation of Bicyclo[3.2.0]hept-3-ene-6-one is studied with oxygen insertion…

  • Kinetics of Acidic Mn(VII) Oxidation of Acetaldehyde in Aqueous and 5% Ethanol-Water Solvents

    Kinetics of Acidic Mn(VII) Oxidation of Acetaldehyde in Aqueous and 5% Ethanol-Water Solvents 1*Latona Dayo Felix, 2Adejoro Ajibade 1*Department of Chemical Sciences, Osun State University, PMB 4494 Osogbo, Nigeria. 2Department of Chemistry, University of Ibadan, Nigeria. Kinetics of acidic Mn(VII) oxidation of acetaldehyde in aqueous and 5% ethanol-water solvents were studied via pseudo-first order condition at λmax 525nm. The reaction showed a first order dependence with respect to acetaldehyde concentration, [Mn(VII)], fractional order to [H+] and independent on the ionic…
