Cnior1de Fluoroarenes (aryl fluorides) are prepared by heating the corresponding diazonium tetrafluoroborates ch. in turn, are obtained by the diazotisation of a suitable aromatic primary amine with aq. NaNO, in sence of fluoroboric acid (HBF) at 273-278 K. NH2 N = NBF4 F NaNO,/HBF4 A O +N+ BF3 273-278 K Boron trifluoride Fluorobenzene Benzenediazonium tetrafluoroborate Aniline This reaction is called Balz-Schiemann reaction.
