Abstract
Novel difluoro-tetraaryl and monofluoro-pentaarylbenzenes were prepared by palladium-catalyzed Suzuki–Miyaura cross-coupling reactions of novel 1,2- and 1,4-difluorotetraiodobenzene and of 1-fluoropentaiodobenzene. These Suzuki–Miyaura reactions allowed a convenient synthesis of fluoro-substituted aryl benzenes. The photophysical properties (absorption and fluorescence) of the products have been studied.
