Abstract:
A composition comprising a (polyfluoroaryl)fluoroanion of aluminum, gallium, or indium supported on a catalyst support material, said (polyfluoroaryl)fluoroanion being selected from those set forth in A) or in B) or in C) as follows:A) a (polyfluoroaryl)fluoroanion represented by the formula:[ER'R""R'""F].sup..crclbar.wherein E is aluminum, gallium, or indium, wherein F is fluorine, wherein R' is a fluoroaryl group having at least one additional substituent other than fluorine, wherein R"" and R'"" each is, independently, (i) a fluoroaryl group having at least one additional substituent other than fluorine, or (ii) a fluorinated aryl group devoid of additional substitution;B) a (polyfluoroaryl)fluoroanion represented by the formula:[ER'R""R'""F].sup..crclbar.wherein E is aluminum, gallium, or indium, wherein F is fluorine, wherein R' is a fluorinated biphenyl group having no more than two hydrogen atoms thereon, and R"" and R'"" each is (i) a fluorinated biphenyl group having no more than two hydrogen atoms thereon, (ii) a fluorinated polycyclic fused ring group having no more than two hydrogen atoms thereon, or (iii) a fluorinated phenyl group having no more than two hydrogen atoms thereon;C) a (polyfluoroaryl)fluoroanion represented by the formula:[E(R.sup.1).sub.n (R.sup.2).sub.3-n F].sup..crclbar.wherein E is aluminum, gallium, or indium, wherein F is fluorine, wherein each R.sup.1 is, independently, a perfluorinated polycyclic fused ring group in which the ring system is totally aromatic or is partially aromatic and partially cycloaliphatic, wherein each R.sup.2 is a pentafluorophenyl group, and wherein n is 1 to 3.
