Title: Process for producing a magnesium di[tetrakis(Faryl)borate] and products therefrom

Abstract: A solution comprising a halomagnesium tetrakis(.sup.F aryl)borate in a liquid organic medium, wherein the liquid organic medium is comprised of one or more liquid dihydrocarbyl ethers, one or more liquid hydrocarbons, one or more liquid halogenated hydrocarbons, or mixtures thereof, is contacted with water. This produces magnesium di[tetrakis(.sup.F aryl)borate] in the organic phase of a two-phase water/liquid organic medium. The magnesium di[tetrakis(.sup.F aryl)borate] can be, but need not be, isolated. A protic ammonium salt, an onium salt, or a triarylmethyl salt can be reacted with the magnesium di[tetrakis(.sup.F aryl)borate] to produce the corresponding protic ammonium, onium, or triarylmethyl tetrakis(.sup.F aryl)borate. The magnesium di[tetrakis(.sup.F aryl)borate] can instead be reacted with a metal salt to form a metal tetrakis(.sup.F aryl)borate. The produced metal tetrakis(.sup.F aryl)borate can be further reacted with a protic ammonium salt, an onium salt, or a triarylmethyl salt to yield a protic ammonium, onium, or triarylmethyl tetrakis(.sup.F aryl)borate. Certain of these tetrakis(.sup.F aryl)borates can be conveniently purified via the formation of a liquid clathrate at ambient temperatures.
