The palladium-catalyseddirect5-arylation of heteroaromatics bearing dicyanovinyls at C2 with aryl bromides via C–H bond functionalisation allows the synthesis of a variety of new conjugated systems in only one step. The nature of the solvent was found to be crucial to perform such arylations. In DMAc, complete decomposition of the dicyanovinyl derivatives was observed, whereas they were found to
