Pentafluorobenzene, 1,2,3,4- and 1,2,3,5-tetrafluorobenzenes, 1-bromo-2,3,4,5-tetrafluorobenzene, and 2H-nonafluorobiphenyl have been nitrated (replacement of H) in high yields to the corresponding mononitro-compounds by use of a mixture of fuming nitric acid, boron trifluoride, and tetramethylene sulphone.
五氟苯,1,2,3,4-和1,2,3,5-四氟苯,1-溴-2,3,4,5-四氟苯和2 H-九氟联苯已在高浓度下进行了硝化(H的取代)通过使用发烟硝酸,三氟化硼和四亚甲基砜的混合物可得到相应的单硝基化合物。
