This invention provides processes for forming halomagnesium tetrakis(
F
aryl)borates, which processes comprise bringing together, in an anhydrous liquid organic medium, at least one boron trihalide; at least one
F
aryl Grignard reagent; and at least one copper compound. Also provided are processes for forming halomagnesium tetrakis(
F
aryl)borates, which processes comprise bringing together, in an anhydrous liquid organic medium, at least one boron trihalide; at least one copper compound; magnesium metal; and at least one polyhaloaromatic compound.
