Disclosed are fluorobenzene derivatives, which are important intermediates for producing herbicidal oxazolidinedione derivatives, and methods of producing them. The fluorobenzene derivatives include compounds of a formula (11): ##STR1## where X is a halogen atom, R.sup.3 is a nitro, amino or isocyanato group or R.sup.1 OCONH, and R.sup.1 is an alkyl or phenyl group. Via the intermediates of the invention, oxazolidinedione derivatives can be produced with high yield.
