ABSTRACT:
A method for producing a borate compound represented by formula (1) is disclosed, comprising a first step of reacting lithium or magnesium or a compound containing lithium or magnesium, a halide represented by formula (2) and a compound represented by formula (3) in a solvent to produce a boronate compound precursor, a second step of reacting lithium or magnesium or a compound containing lithium or magnesium, a halide represented by formula (4) and the boronate compound precursor obtained in the first step in a solvent to produce a borate metal salt, and a third step of adding an onium halide represented by formula (5) to the borate metal salt obtained in the second step to effect ion-exchange reaction (the formulae are as described in the specification).
