  • Process for the functionalization of sp-H carbons using frustrated lewis pair catalysts
    Patent number: 10988488
    Abstract: A catalytic process for the metal-free functionalization of sp2-carbons is described herein. The catalytic process is suitable for forming borylated alkenes, arenes and heteroarenes and comprises the use of catalysts comprising a Frustrated Lewis Pair (FLP).
    Type: Grant
    Filed: April 21, 2016
    Date of Patent: April 27, 2021
    Assignee: UNIVERSITÉ LAVAL
    Inventors: Frederic-Georges Fontaine, Marc-Andre Legare, Marc-Andre Courtemanche
  • Precatalysts and process for the metal-free functionalization of SP2 carbons using the same
    Patent number: 10821429
    Abstract: Precatalysts and catalytic processes for the functionalization of sp2-carbons using the precatalysts are described herein. The precatalysts comprise an intramolecular Frustrated Lewis Pair (FLP) that is generated in situ from the corresponding precatalyst fluoroborate salts. The precatalyst fluoroborate salts are deprotected in situ to generate catalysts including intramolecular FLPs for the dehydrogenative borylation of alkenes, arenes and heteroarenes. The catalytic process comprises contacting a precatalyst, a functionalization reagent; and a substrate comprising a sp2-H carbon, under conditions to provide a substrate comprising a functionalized sp2 carbon.

  • Precatalysts and process for the metal-free functionalization of SPcarbons using the same
    Patent number: 10258976
    Abstract: Precatalysts of formula I and IV, and processes for the functionalization of SP2-carbons using the same are described herein. The precatalysts comprise a fluoroborate salt protected intramolecular frustrated lewis pair (FLP). The precatalysts are bench stable with improved stability towards moisture and/or air. The precatalysts can be used to generate in situ the corresponding FLP catalyst.
