    • Abstract


      Synthesis via organo-lithium compounds is reviewed. An anomalous aromatic substitution via halogen-metal exchange is described. Here, the substitution does not occur at the position where the halogen was present; but at an alternate position. A mechanism is advanced, in which the halogen-metal exchange is proposed as being faster than the hydrogen(acidic)-metal exchange.
