Abstract
(Pentafluorophenyl) Group 11 and 12 metal compounds and processes for preparing (pentafluorophenyl) Group 11 and 12 metal compounds are disclosed. Also, disclosed are processes for preparing (pentafluorophenyl) Group 13 or 15 metal compounds useful as Lewis acids. Compositions with low levels of base impurities and products produced by the novel processes are also disclosed.

A process, comprising the steps of:
- a. contacting, in a bulk melt state:
- i. pentafluorobenzoic acid with a Group 11 or 12 metal oxide, a Group 11 or 12 metal hydroxide, a Group 11 or 12 metal carbonate, or a Group 11 or 12 metal acetate under neutralizing conditions;
- or
- ii. a Group 1 or 2 metal salt of pentafluorobenzoic acid with a Group 11 or 12 metal halide;
- to form a Group 11 or 12 pentafluorobenzoate;
- b. removing volatiles;
- and
- c. decarboxylating said Group 11 or 12 pentafluorobenzoate to form a (pentafluorophenyl) Group 11 or 12 metal compound.
