electrophilic aromatic substitution allows the synthesis of monoacylated
products from the reaction between arenes and acyl chlorides or
anhydrides. The products are deactivated, and do not undergo a second
substitution. Normally, a stoichiometric amount of the Lewis acid
catalyst is required, because both the substrate and the product form
The Friedel-Crafts Alkylation may give polyalkylated products, so the Friedel-Crafts Acylation is a valuable alternative. The acylated products may easily be converted to the corresponding alkanes via Clemmensen Reduction or Wolff-Kishner Reduction.
