A process for producing nucleus-fluorinated aromatic carboxylates, which comprise nucleus-fluorinating aromatic carboxylates of the following formula (1) with a fluorinating agent to obtain nucleus-fluorinated aromatic carboxylates of the following formula (2):
wherein R¹ is an alkyl group, an aryl group or a fluoroalkyl group, each of A and B is at least one member selected from the group consisting of a hydrogen atom, a halogen atom, an alkyl group, an aryl group and a fluoroalkyl group, and n and m are integers satisfying m + n = 6, provided that m is 1 or 2, provided that at least one A is an activated chlorine or bromine atom, and B corresponding to such an activated chlorine or bromine atom is a fluorine atom.
