摘要：
Sixteen 2,2'-bifurans with aryl substituents are reported. The copper-mediated oxidative coupling of lithium salt of furan led to the formation of 2,2'-bifuran, which was brominated with either 2 eq. or 4 eq. NBS to afford 5,5 '-dibromo-2,2'-bifuran and 3,3',5,5'-tetrabromo-2,2'-bifuran. The palladium-catalyzed Suzuki reactions between dibromo or tetrabormo-bifuran and arylboronic acid were employed to furnish the title compounds, which were characterized by NMR spectra and mass spectra.
