The influence of both electron-withdrawing and electron-donating substituents such as nitro, nitrile, chloro, bromo and methoxy at C-3 on fluorobenzenes for their palladium-catalysed direct C-2 arylation has been explored. With electron-withdrawing substituents, the reaction proceeds nicely using 2-4 mol% of an air-stable palladium complex and potassium pivalate/dimethylacetamide (PivOK/DMA) as catalytic system; and in general, a very regioselective arylation at C-2 was observed. Moreover, a variety of substituents on the aryl bromide coupling partner, such as benzoyl, formyl, nitro, nitrile, chloro and methyl, and also heteroaryl bromides were tolerated.
