title: Dimerization of cyclopropenes to bifurans using tandem metal relay catalysis.
abstract: An efficient synthesis of bifurans via dimerization of cyclopropenes has been successfully developed using a copper-promoted cycloisomerization and palladium-catalyzed dimerization cascade. These novel bifuran structures possess interesting optoelectronic properties.
