Catalytic intermolecular direct arylation of perfluorobenzenes.

J. Am. Chem. Soc. 128 , 8754, (2006)

Penta-, tetra-, tri-, and difluorobenzenes undergo direct arylation with a wide range of arylhalides in high yield. Inverse reactivity is observed compared to the common electrophilic aromatic substit...
