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

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