Abstract

The liquid ethereal medium or liquid hydrocarbyl medium of a solution or slurry of an alkali metal tetrakis(Faryl)borate is substituted with at least one halogenated hydrocarbon, without isolating the alkali metal tetrakis(Faryl)borate, to form a new slurry or solution. At least a portion of the new solution is mixed together with a salt selected from a) a protic ammonium salt, b) an onium salt, and c) a triarylmethyl salt, to produce a protic ammonium tetrakis(Faryl)borate, an onium tetrakis(Faryl)borate, or a triarylmethyl tetrakis(Faryl)borate.
