  • Addition to aqueous solutions of aryldiazonium salts usually results in precipitation of the diazonium tetrafluoroborates, which are often stable enough to be isolated, and can undergo various reactions in non-aqueous solvents. For hydrodediazoniation in the presence of formamide, see: J. Chem. Soc., Perkin 1, 873 (1986). Probably their most important use is the Schiemann (or Balz-Schiemann) synthesis of aryl fluorides in which the tetrafluoroborate salt is heated neat or in an inert solvent. For examples, see: Org. Synth. Coll., 2, 188, 295, 299 (1943). Reviews: Org. React., 5, 193 (1949); Adv. Fluorine. Chem., 4, 1 (1965). See also Hexafluorophosphoric acid, L15728.

  • 概述:氟硼酸又称“氢硼氟酸”、“四氟合硼氢酸”。化学式HBF4。分子量87.81。无色透明液体。有毒!具有强烈的腐蚀性,不能久藏于玻璃容器中。沸点130℃,同时缓慢分解。溶于水和乙醇,与水共热分解生成氟氧硼酸和三氧化硼(可浓缩至30%),溶液呈强酸性,常温下不腐蚀玻璃。氟硼酸是个强酸,仅存在于溶液中,常见的氟硼酸盐为四氟硼酸钾。 制法:可将浓氢氟酸与硼酸反应而制得。 用途:用于冶炼轻金属和电镀等,即使极稀溶液也能用作发酵抑制剂,还供制备重氮盐、缩醛催化剂,在镁离子和钾离子存在下作测定钠的试剂。以苯胺为原料在浓的盐酸中与亚硝酸钠反应,生成重氮盐,再在低温下(-10℃),使重氮盐与氟硼酸反应,最后热解,可制得氟苯。
