Abstract:
A process for producing tetrakis(fluoroaryl) borate expressed by Formula (5): where each of R1-R10 represents a hydrogen atom, a fluorine atom, a hydrocarbon group, or an alkoxy group, provided that at least one of R1-R5 represents a fluorine atom and at least one of R6-R10 represents a fluorine atom, M represents a hydrogen atom, an alkali metal, an alkaline earth metal, or an alkaline earth metal halide, n represents 2 or 3, and m represents 1 when M represents a hydrogen atom, an alkali metal, or an alkaline earth metal halide, and 2 when M represents an alkaline earth metal,comprising removing an ether compound expressed by Formula (6): R11â€”Oâ€”Yâ€”Oâ€”R12â€ƒâ€ƒ(6) where each of R11 and R12 represents a hydrocarbon group which may include a substituent group containing a hetero atom, and Y represents a bivalent hydrocarbon group, from a tetrakis(fluoroaryl)borateâ€¢ether complex expressed by Formula (4): where each of R1-R10 represents a hydrogen atom, a fluorine atom, a hydrocarbon group, or an alkoxy group, provided that at least one of R1-R5 represents a fluorine atom and at least one of R6-R10 represents a fluorine atom, each of R11 and R12 represents a hydrocarbon group which may include a substituent group containing a hetero atom, Y represents a bivalent hydrocarbon group, M represents a hydrogen atom, an alkali metal, an alkaline earth metal, or alkaline earth metal halide, n represents 2 or 3, and m represents 1 when M represents a hydrogen atom, an alkali metal, or an alkaline earth metal halide, and 2 when M represents an alkaline earth metal.
