Abstract:
The present invention relates to a process for manufacturing fluoroaromatics of formula (I), A-F (I) comprising step a) diazotization of aminoaromatics of formula (II) in anhydrous HF with an aqueous solution of a diazotizing agent; followed by step b) thermic decomposition of the diazonium salt of formula (III) resulting from step a); wherein the variables are defined according to the description.
