The palladium-catalyzed cross-coupling reaction of iodinanes (iodonium salts and iodanes) with organoboroncompounds to form carbon-carbon bonds was achieved at ambient temperature under aqueous conditions in the absence of base. Coupling of phenylboronic acid with diphenyliodonium tetrafluoroborate in the presence of Pd(PPh(3))(4) (0.2 mol %) or Pd(OAc)(2) (0.2 mol %) under aqueous conditions gave
