From the standpoint of green chemistry, tris(pentafluorophenyl)gallium (7) and tris(pentafluorophenyl)aluminum (8) outperform all previously explored perfluoroarylated Lewis acids (PFLAs) for the polymerization of isobutene. In comparison to other PFLA based systems, 7 and 8 do not require ultrahigh purity monomer, toxic chlorinated solvents, or expensive and highly sensitive initiators (e.g., met ...
