✦ Synopsis

Potassium pentafluorophenyl-and trifluorovinyltrifluoroborates, both containing electron-poor organo groups, reacted with iodobenzene and p-substituted iodobenzenes in the presence of palladium compounds and stoichiometric amounts of silveroxide to the fluorinated cross-coupling products in very good yields. Substituted bromobenzenes were less efficient substrates.
