Conclusions

  1. 1.

    The bromination of a complex of acetophenone with aluminum chloride with the formation of m-bromoacetophenone, contrary to the literature data, can be carried out successfully in a suitable solvent (dichloroethane, chloroform), and the excess of aluminum oxide sufficient for the reaction can be reduced to 0.5 mole, instead of 1.5 moles in work without a solvent.

     
  2. 2.

    The dissociation of the complex observed when the dilution is increased or the solvent is replaced, leads to the formation of phenacyl bromide, the product of bromination of the side chain.
