  • Lewis acid catalyzed halogenation of activated carbon atoms
    Patent number: 8618320
    Abstract: A practical and efficient method for halogenation of activated carbon atoms using readily available N-haloimides and a Lewis acid catalyst has been disclosed. This methodology is applicable to a range of compounds and any halogen atom can be directly introduced to the substrate. The mild reaction conditions, easy workup procedure and simple operation make this method valuable from both an environmental and preparative point of view.
    Type: Grant
    Filed: February 24, 2012
    Date of Patent: December 31, 2013
    Assignee: Japan Science and Technology Agency
    Inventors: Yanhua Zhang, Hisashi Yamamoto, Kazutaka Shibatomi
