  2. 1. Synthesis of Organoboronic Acids and Applications in Asymmetric Organocatalysis

    Author : Sybrand Jonker; Kálmán Szabó; Jörg Pietruszka; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Boronic acid; BINOL; allylboration; propargylation; homologation; stereoselective synthesis; asymmetric synthesis; organocatalysis; allylboronic acid; allenylboronic acid; organisk kemi; Organic Chemistry;

    Abstract : Allyl- and allenylboronic acids are valuable reagents in organic synthesis due to their configurational stability and high reactivity. Few allyl- and allenylboronates are commercially available. Therefore, both the preparation and synthetic application of these organoboronic acids are subjects of study. READ MORE

  4. 2. Multifunctional Polymer Materials: From Synthesis to Disinfection

    Author : Haiyue Gong; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecularly imprinted polymer; Antibacterial; Ag nanoparticles; Antibiotic; Boronic acid; Polyethylenimine; Quaternary ammonium;

    Abstract : Polymer materials have wide applications in many industries, such as the food, pharmacy, construction, textile, and cosmetics industries. For the past few years, polymer materials have drawn the attention of scientists and engineers as a good disinfectant due to their advanced manufacturing methods, large surface areas, good stability, and lowcost.
