ABSTRACT:
A method of producing a high-purity triarylborane with high yield by reacting, in a solvent inert to the reaction product, a 1.0-8.0 mol/L boron halide solution with a 0.1-3.0 mol/L aryl magnesium halide solution in a straight chain ether solvent, where the molar ratio of aryl magnesium halide to boron trihalide is 3.1-3.5 to 1.0, respectively, and then the straight chain ether solvent is distilled from the reaction mixture. Distillation crystallizes out the halogenated magnesium salt which is produced as a by-product, increasing the recovery rate of the product.
