- 方法一:用镁屑、溴化苯及乙醚溶液和碘片先合成格氏试剂，其含量一般为39%-43%左右。然后，将格氏试剂与硼酸三甲酯反应，水解，乙醚提取，过滤。滤液用氯仿提取，在提取液中加入食盐，盐析得到白色沉淀（四苯硼钠粗品）。再用丙酮提取，滤除食盐，滤液在室温下减压浓缩，结晶，用丙酮重结晶，在30-40℃干燥即得成品。

- 上游原料:溴 --> 氯化钠 --> 正丁醇 --> 碘 --> 溴苯 --> 硼酸三甲酯 --> 硼酸 --> 格氏试剂
- 用途二:酯交换法制取碳酸酯的缩聚催化剂。也用于钾、钠和几利含氯有机化合物的测定，例如于分析胛肥及血液中的钾。
- 无气味。对光敏感。微吸湿。200℃以下稳定。易溶于水、无水乙醇、甲醇和丙酮，微溶于乙醚和氯仿，几乎不溶于石油醚。在水溶液中逐渐分解而浑浊，矿酸能促进分解，加入数滴稀氢氧化钠溶液可延缓分解。水溶液的pH调节到约5时，可以在室温中保存，如在45℃，该溶液可保存5天而不变质。有刺激性。
