Target entity: Brown hydroboration
Context triple: [Herbert C. Brown, knownFor, Brown hydroboration]
  • A. Barton reaction
    The Barton reaction is an organic photochemical transformation that converts nitrite esters into δ-nitroso alcohols via intramolecular hydrogen abstraction and radical rearrangement.
  • B. Barton–McCombie deoxygenation
    Barton–McCombie deoxygenation is an organic chemistry reaction that converts alcohols into the corresponding hydrocarbons via radical-mediated removal of the hydroxyl group.
  • C. Corey–Bakshi–Shibata reduction
    The Corey–Bakshi–Shibata reduction is a widely used asymmetric organic reaction that enantioselectively reduces ketones to chiral alcohols using a chiral oxazaborolidine catalyst and borane.
  • D. Sharpless asymmetric dihydroxylation
    Sharpless asymmetric dihydroxylation is a landmark chemical reaction that uses chiral catalysts to add two hydroxyl groups across an alkene with high enantioselectivity, revolutionizing asymmetric synthesis in organic chemistry.
  • 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. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
