The palladium-catalyseddirect5-arylation of furan or thiophenederivatives bearing CH2NHR substituents (with R = COMe or CO2tBu) generally proceeds in good yields by using a catalysts loading of only 0.1-2 mol-%. A wide range of functions such as acetyl, propionyl, formyl, ester, nitrile, trifluoromethyl or fluoro on the aryl bromide is tolerated. Higher yields were generally obtained in the presence
