Target entity: Suzuki–Miyaura coupling
Context triple: [Buchwald–Hartwig amination, relatedTo, Suzuki–Miyaura coupling]
  • A. Suzuki coupling chosen
    Suzuki coupling is a widely used palladium-catalyzed cross-coupling reaction that forms carbon–carbon bonds between organoboron compounds and organic halides, fundamental in organic synthesis and pharmaceutical chemistry.
  • B. Sonogashira coupling
    Sonogashira coupling is a palladium-catalyzed cross-coupling reaction that forms carbon–carbon bonds between terminal alkynes and aryl or vinyl halides, widely used in organic and materials synthesis.
  • C. Kumada coupling
    Kumada coupling is a palladium- or nickel-catalyzed cross-coupling reaction between Grignard reagents and organic halides used to form carbon–carbon bonds in organic synthesis.
  • D. Negishi coupling
    Negishi coupling is a palladium- or nickel-catalyzed cross-coupling reaction that forms carbon–carbon bonds between organozinc reagents and organic halides, widely used in organic synthesis.
  • E. Buchwald–Hartwig amination
    The Buchwald–Hartwig amination is a palladium-catalyzed cross-coupling reaction that forms carbon–nitrogen bonds by coupling aryl (or vinyl) halides with amines, widely used in the synthesis of pharmaceuticals and fine chemicals.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
