A benzene derivative substituted with a heterocyclic ring represented by the general formula: ##STR1## wherein R represents a cycloalkyl group having 3 to 8 carbon atoms, X represents a halogen atom, and Z represents ##STR2## in which said cycloalkyl group may be substituted with an alkyl group having 1 to 6 carbon atoms, a process for preparing the same, and a herbicidal agent comprising the above compound as an active ingredient are disclosed. The compound has an excellent effect in that the compound exhibits a markedly high herbicidal effect on weeds in the field and the paddy field at a low dose and yet exhibits markedly low noxious effects on main crops.

Benzene derivatives substituted with heterocyclic ring, and herbicides

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.
