Target entity: Barton decarboxylation
Context triple: [Barton–McCombie deoxygenation, relatedReaction, Barton decarboxylation]
  • 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. Stork–Danheiser rearrangement
    The Stork–Danheiser rearrangement is an organic reaction that transforms certain allylic alcohol derivatives into rearranged carbonyl compounds via a sigmatropic shift, widely used in complex molecule synthesis.
  • D. Heck reaction
    The Heck reaction is a palladium-catalyzed cross-coupling between alkenes and aryl or vinyl halides, widely used in organic synthesis to form carbon–carbon bonds.
  • E. Norrish reaction
    The Norrish reaction is a photochemical process in organic chemistry involving the cleavage and rearrangement of carbonyl compounds under ultraviolet light, fundamental to understanding photodegradation and radical mechanisms.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
