    摘要: 1-(3-Substituted benzyl)-3-halogeno-4-(1-halogenoalkyl)-2-pyrrolidinones of the general formula (I):
    where X represents a hydrogen atom or halogen atom, Y and Z each represents a chlorine atom or bromine atom, and R represents an alkyl group with 2 to 4 carbon atoms, are herbicides useful in rice paddy fields to control weeds therein, especially Echinochloa crusgalli and can be produced subjecting the corresponding 3-dihalogeno compounds to dehalogenation to remove one of the halogen atoms or by cyclizing a 2,2-dihalogenoacetamide derivative represented by the general formula (II) under the presence of an appropriate catalyst;
    in which X, Y, Z and R respectively have the same meanings as described above.
