Preparation of aliphatically substituted fluorobenzenes |
| abstract |
Aliphatically substituted fluorobenzenes of the general formula I <IMAGE> I where R is an aliphatic or cycloaliphatic radical, n is 2, 3 or 4 and X is hydrogen, fluorine, chlorine or bromine, are prepared by diazotization of the corresponding aniline derivative of the general formula II <IMAGE> II in the presence of tetrafluoboric acid and decomposition of the resulting diazonium tetrafluoborate of the general formula III <IMAGE> III by a process in which the decomposition reaction is carried out simultaneously with the diazotization reaction, in the presence of elemental copper and/or copper(I) and/or copper(II) salts and at from -15 DEG to 80 DEG C. |
