Rhodium-Catalyzed ortho Acylation of Aromatic Carboxylic Acids. -The catalyst [Rh(cod)Cl]2 is found to direct the acylation of benzoic acids with anhydrides into the ortho position. Combined with subsequent decarboxylation ketones of type (IV) can be obtained. Interestingly, the use of Boc2O as anhydride yields diarylketones as esters (VII) after alkylation. -(MAMONE, P.; DANOUN, G.; GOOSSEN*, L. J.; Angew. Chem., Int.
