Functionalized anthraquinones, fluorenones and benzocoumarines were also prepared by this methodology. Regioselctive Suzuki-Miyaura cross-coupling reactions of 2,4,5,6-tetrachloropyrimidine and 2,3,4,5-tetrabromofuran provided an expedient synthesis of mono-, di-, tri- and tetraaryl-pyrimidines and di- and tetraarylfurans.
