HOX addition: Halohydrins

HOX Addition to Alkenes: Halohydrins

  • Markovnikov addition, anti-addition.
  • Stereochemistry controlled by backside attack of H2O to halonium ion.
  • Rearrangements don't occur, rearrangements only occur with carbocation
    intermediates.
  • Evidence for this mechanism.
    • No observation of rearrangements
    • anti-addition product.
