Alkoxy-mercuration of Alkenes

  • Page ID
  • The alkoxymercuration reaction is similar to oxymercuration reaction, except alcohol is used instead of water.

    Reactions #3 and #4 are examples of this two-step procedure. Note that the alcohol reactant is used as the solvent, and a trifluoroacetate mercury (II) salt is used in preference to the acetate (trifluoroacetate anion is a poorer nucleophile than acetate). The mechanism of alkoxymercuration is similar to that of oxymercuration, with an initial anti-addition of the mercuric species and alcohol being followed by reductive demercuration.
