  • FUNCTIONALISED GRAPHENE
    Publication number: 20190144284
    Abstract: Graphene is chemically modified by a process resulting in the introduction of functional groups located only at an edge of the graphene plane. The functionalised graphene finds uses in numerous applications and further chemical synthesis, including a process for coupling an organic or inorganic moiety to the graphene plane via the edge-located functional group. The disclosed products and processes provide highly flexible platforms for the integration of graphene into a variety of applications.
    Type: Application

  • Regioselective sulfation
    Patent number: 5874548
    Abstract: A direct method is disclosed for the regioselective sulfation of an organic molecule having optionally derivatized hydroxyl groups on at least two adjacent carbon atoms. The method comprises the treatment of a di-(optionally substituted alkyl and/or aryl) stannylene acetal derivative of the molecule with an electrophilic sulfating agent, preferably sulfur trioxide/trimethylamine. The disclosed method is useful for the selective sulfation of a variety of mono-, di- and oligosaccharides. Novel saccharides prepared according to this method are also disclosed.
