Ortholithiations of a range of arenes mediated by lithium diisopropylamide (LDA) in THF at -78 °C reveal substantial accelerations by as little as 0.5 mol % of LiCl (relative to LDA). Substrate dependencies suggest a specific range of reactivity within wh

The invention relates to a method for the production of substituted aromatic compounds by producing lithium arylene and by reacting it with suitable electrophiles. The method comprises the following steps (step 1); an aryl lithium compound ( auxiliary base'') is initially produced by reacting a halogen aromatic compound with lithium metal; said compound is subsequently (step 2) reacted for deprotonation of the aromatic substrate in order to form the corresponding lithium aromatic compound which is subsequently (step 3) reacted with a corresponding electrophile to form the desired substituted aromatic compound, see page 2 of the description.
