Zusammenfassung:	A process for producing boron compounds represented by general formula (1) which comprises the first step of producing a metal borate represented by general formula (4) through reactions of a lithium, magnesium, or a lithium compound with a compound represented by general formula (2) and a compound represented by the general formula (3) of R2-Y and the second step of adding an onium halide represented by the general formula (5) of Z+.X- to the metal borate (4) to cause the borate to undergo an ion-exchange reaction (the symbols in the formulae having the same meanings as in the specification). This process can provide high-purity boron compounds represented by general formula (1) useful as a photopolymerization initiator or a light-absorbing decoloring agent in high yields in a short time.
