    A modification of polystyrene supported palladium(II) complex as effective catalyst for Mizoroki‐Heck reaction
    (Journal of Scientific Research and Development, 2016) Siti Kamilah Che Soh; Siti Aminah Jusoh; Mohd Sukeri Mohd Yusof; Wan M. Khairul
    Chloromethylated polystyrene cross-linked with 5% divinylbenzene (PS5) has been successfully functionalized with phenyldithiocarbazate ligand (PS5-PDC). The polymer was used as solid support for anchoring the palladium metal (PS5-PDC-Pd). The properties of dark colored polymer, impregnated with palladium complex was then characterized by various spectroscopic and analytical techniques namely Fourier Transform Infrared (FTIR), elemental chemical analysis CHNS, Thermogravimetric analysis (TGA), BET surface area, powder X-ray Diffraction (XRD), Inductively Coupled Plasma-Optical Emission Spectrometer (ICP-OES) and Scanning Electron Microscopy/Energy Dispersive X-ray (SEM-EDX). Supported catalyst of PS5-PDC-Pd was then tested in the Mizoroki-Heck reaction of 4-bromoacetophenone with methyl acrylate. The reaction was monitored by GC-FID. Preliminary results showed that supported catalyst could be used in at least three consecutive Mizoroki-Heck reactions with the same catalytic activity.

    Synthesis and Characterization of New Metal- Organic Framework Derived from 6- (Methoxycarbonyl) Pyridine-2-Carboxylic Acid as Application for Hydrogen Storage Materials
    (International Journal of Applied Chemistry, 2016) Maisara Abdul Kadir; Nafisah Mansor; Wan M. Khairul; Mohd Sukeri Mohd Yusof; Mohammad Ismail
    In this study, a new organic linker namely 6-(pyrimidin-2-ylcarbamoyl)-pyridine-2- carboxylic acid methyl ester (L1) has been successfully synthesized. Along with this discovery, two metal-organic frameworks (MOFs) which derived from L1 and 6- (methoxycarbonyl)pyridine-2-carboxylic acid (L), have also been synthesized and characterized by using combination of spectroscopic techniques such as Infrared (IR), Nuclear Magnetic Resonances (NMR), Thermal Gravimetric Analysis (TGA) and Xray crystallography.
