The influence of fluoro-substituents on secondary and tertiary benzamides on the regioselectivity of palladium-catalysed direct arylations was studied. With most (poly)fluoro-substituted tertiary benzamides, the arylations proceed very regioselectively at ortho-positions of the fluoro substituents using 1 mol% of air-stable palladium catalysts and PivOK/DMA as the reaction conditions. With the 3,5
