A method for the production of a fluorine-containing aromatic compound is provided which allows the relevant reaction to proceed in a standard reaction vessel such as, for example, a glass vessel at room temperature under an ambient pressure without requiring provision of such special devices as have been necessary heretofore or adoption of harsh reaction conditions. This method comprises causing an aromatic compound (A) having a cyclic skeletal part of 6 to 16 carbon atoms containing a plurality of --C(.dbd.O)X groups, wherein X stands for a hydrogen atom, a halogen atom, or an alkyl group of 1 to 10 carbon atoms, and having the remaining hydrogen atoms unsubstituted or partly or wholly substituted with at least one species of halogen atom to react with a compound (B) represented by the formula: ##STR1## wherein R.sup.1 and R.sup.2 independently stand for an alkyl group of 1 to 6 carbon atoms or a phenyl group.
