  • SILYLATIONS OF AROMATIC SUBSTRATES WITH BASE-ACTIVATED ORGANOSILANES
    Publication number: 20180155271
    Abstract: The present disclosure describes methods for silylating aromatic organic substrates, and associated chemical systems, said methods comprising or consisting essentially of contacting the aromatic organic substrate with a mixture of (a) at least one organosilane and (b) at least one strong base, under conditions sufficient to silylate the aromatic substrate.
    Type: Application

  • Reactions of aromatic substrates with base-activated hydrosilanes-silylations and reductive cleavage
    Patent number: 9908840
    Abstract: The present invention describes chemical systems and methods for reducing C—O, C—N, and C—S bonds, said system comprising a mixture of (a) at least one organosilane and (b) at least one strong base, said system being substantially free of a transition-metal compound, and said system optionally comprising at least one molecular hydrogen donor compound, molecular hydrogen, or both.
    Type: Grant
