class of compounds mainly due to their wide range of biological and technological applications. The development of a new methodology for their synthesis, involving an Ullmann-type coupling followed by an intramolecular C–H arylation, catalyzed by copper in a domino fashion, is reported. A variety of para-substituted phenols are amenable to this methodology, affording the desired products in moderate to
