Arylated bithiophenes, which are useful compounds due to their coordination and/or physical properties, can be easily prepared by palladium-catalysed C–H bond activation of heteroaromatics followed by arylation using electron-deficient aryl bromides. A variety of 5-arylated 2,2′-bithiophenyl derivatives have been prepared. Good yields were generally obtained by using the air-stable [PdCl(dppb)(C3H5)]
