Abstract

In this paper we report a copper-mediated intermolecular coupling of zirconacyclopentadienes with dihalo aromatic rings. This reaction can provide a novel preparative method of fused aromatic ring compounds. Yields were dependent on the amount of dimethylpropylene(urea) (DMPU). When 1.0 equiv of DMPU was used, the yields were 50-60%. The best yields were obtained when 2.5-3.0 equiv of DMPU was used. The use of HMPA instead of DMPU gave the same result.
