Pd(0)-catalyzedintermolecular arylation of sp(3) C-H bonds has been achieved using PR(3)/ArI. This protocol can be used to arylate a variety of aliphatic carboxylic acid derivatives, including a number of bioactive drug molecules. The use of fluorinated aryl iodides also allows for the introduction of fluorine into a molecule of interest.

Protocols to effect β-arylation of sp3 C–Hbonds via Pd(II)/(IV) and Pd(0)/(II) catalytic cycles have been achieved using a newly developed monodentate CONHC6F5 directing group. These reactions provide an unprecedented means to functionalize sp3 C–Hbonds in aliphatic carboxylic acid-derived substrates.
