New directions: The carboxylicacid functional group directs the ortho acylation of benzoic acids with carboxylic anhydrides in the presence of a rhodium catalyst (see scheme; cod=cyclo‐1,5‐octadiene). The acylation at the ortho position is complementary to the meta selectivity of Friedel–Crafts reactions. The resulting products can undergo protodecarboxylation to deliver an aryl ketone.
