palladium(II)-catalyzed decarboxylative protocol for the synthesis of aryl ketones has been developed. The addition of TFA was shown to improve the reaction yield and employing THF as solvent enabled the use of solid nitriles and in only a small excess. Using this method, five different benzoic acids reacted with a wide range of nitriles to produce 29 diverse (hetero)aryl ketone derivatives in up to 94% yield.

A Pd/PCy3/Ag2CO3 (Cy = cyclohexyl) catalytic system was found to promote decarboxylativearylation through the combination of decarboxylation and C–H bond functionalization. This protocol features a good substrate scope of aromatic carboxylic acids as well as a broad range of functional groups and provides the products in high yields.
