Pentafluorophenylation of perfluoroarenes with C6F 5Si(CH3)3 was investigated by using NMR and MALDI-TOF-MS techniques. Successive multiple pentafluorophenylation easily occurred not only on the para-position but also on the ortho-positions to provide perfluorinated p-phenylene and m-phenylene compounds. The perfluoroarenes having electron-withdrawing substituents provided oligo- to poly-(phenylene)s depending on the added amounts of C6F 5Si(CH3)3, while the perfluoroarenes having electron-donor substituents gave H(C6F4)nF polymers produced from C6F5H, which was the decomposed product of C6F5Si(CH3)3.
