N-(2-chloro-4-nitrophenyl)-benzenesulfonamide derivatives are represented by the following general formula:
wherein X and Y individually mean a hydrogen or chlorine atom and Z denotes a chlorine atom or trifluoromethyl group. Such derivatives are useful as agricultural agents, e.g. fungicides for combatting soil-borne diseases. The derivatives are prepared by reacting a benzenesulfonyl chloride compound represented by
with 2-chloro-4-nitroaniline in the presence of a base.
