Target entity: Hofmann rearrangement
Context triple: [August Wilhelm von Hofmann, knownFor, Hofmann rearrangement]
  • A. 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.
  • B. Arbuzov rearrangement
    The Arbuzov rearrangement is an organic reaction in which trialkyl or triaryl phosphites react with alkyl halides to form phosphonates, widely used in the synthesis of organophosphorus compounds.
  • C. Eschenmoser–Claisen rearrangement
    The Eschenmoser–Claisen rearrangement is a variant of the Claisen rearrangement in organic chemistry that converts allylic alcohols and amides into γ,δ-unsaturated carbonyl compounds via a [3,3]-sigmatropic rearrangement.
  • D. Claisen rearrangement
    The Claisen rearrangement is a pericyclic [3,3]-sigmatropic rearrangement in organic chemistry that converts allyl vinyl ethers (or related systems) into γ,δ-unsaturated carbonyl compounds with high stereospecificity.
  • E. Overman rearrangement
    The Overman rearrangement is an organic chemical reaction that converts allylic alcohol derivatives into allylic amines via a [3,3]-sigmatropic rearrangement of allylic trichloroacetimidates.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
