Pd-catalyzed decarboxylative cross coupling of potassiumpolyfluorobenzoates with arylbromides, chlorides, and triflates is achieved by using diglyme as the solvent. The reaction is useful for synthesis of polyfluorobiaryls from readily accessible and nonvolatile polyfluorobenzoate salts. Unlike the Cu-catalyzed decarboxylation cross coupling where oxidative addition is the rate-limiting step, in

reaction of potassium polyfluorobenzoates with aryl iodides and bromides was achieved in diglyme or DMAc at 130 or 160 °C in the presence of 10–20 mol% of a 1,10-phenanthroline-functionalized MCM-41-immobilized copper(I) complex, [MCM-41-Phen-CuI], yielding a variety of polyfluorobiaryls in good to excellent yields. This heterogeneous copper(I) complex could easily be prepared via a simple procedure

for the coupling of perfluorobenzoates with arylhalides and pseudohalides is described. Aryl iodides, bromides, chlorides, triflates, and tosylates participate in these transformations to afford the products in good yields. Penta-, tetra-, and trifluorinated biaryl compounds are obtained using these newly developed Ni-catalyzed decarboxylativecross-coupling reactions.

We report a Pd-catalyzed direct arylation of polyfluoroarenes with aryl iodides. The advantages of this reaction are its high reaction efficiency, excellent functional group compatibility, mild reaction conditions (70 degrees C), inexpensive PPh3 ligand, and use of pure water as reaction medium. The usefulness of this reaction has also been demonstrated by rapid preparation of highly functionalized polyfluoroarenes via iterative Pd-catalyzed C-H bond functionalization.
