Target entity: Chichibabin reaction
Context triple: [Boris Chichibabin, notableWork, Chichibabin reaction]
  • A. 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.
  • B. 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.
  • C. 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.
  • D. Robinson annulation reaction
    The Robinson annulation reaction is a classic organic chemistry transformation that forms six-membered rings by combining a Michael addition with an intramolecular aldol condensation, widely used in the synthesis of complex cyclic molecules and natural products.
  • E. Diels–Alder reaction
    The Diels–Alder reaction is a fundamental organic chemistry cycloaddition that forms six-membered rings by combining a conjugated diene with a dienophile in a single, stereospecific step.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
