研究了间苯二胺经Ｓｃｈｉｅｍａｎｎ反应来制备间二氟苯，在－１２℃以下的低温将间苯二胺的冷盐酸溶液慢慢滴加到新制备的亚硝酸溶液中，然后加入氟硼酸溶液，能得到９０％收率的间苯二重氮双氟硼酸盐。对上述重氮盐进行热分解可以得到８０％收率的间二氯苯。
M-difluorobenzene was prepared by Schiemann reaction of m-phenylenediamine. The cold hydrochloric acid solution of m-phenylenediamine was slowly added dropwise to the freshly prepared nitrous acid solution at a temperature of -12 ° C or lower, and then a solution of boronic acid , Can be obtained in 90% yield of m-diazodifluoroborate. The diazonium salt was thermally decomposed to give m-dichlorobenzene in 80% yield.
