A facile cobalt(III) catalyzed C–H activation of arenes with substituted (benz)imidazoles as directing groups (DG) is reported. The strategy was utilized for the synthesis of polyheteroarenes when appropriate substrates were treated with diarylacetylenes as the coupling partner. The desired compounds were synthesized in moderate to excellent yield. A putative reaction mechanism is proposed. The final compounds revealed photoluminescence properties. © 2018 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
