Description

  The present invention relates to a sulfonylamidine derivative, a production method thereof, and use thereof.

Conventionally, pest control agents such as various insecticides have been studied (for example, Patent Documents 1 to 3). Patent Documents 1 to 3 disclose pest control agents using amidine compounds.
However, Patent Document 1 relates to an agricultural and horticultural fungicide and does not disclose a perfluoroalkylsulfonyl group as a nitrogen substituent of a carbonylimino group (C = N).
Patent Document 2 discloses an amidine derivative used for an insecticide, but no perfluoroalkylsulfonyl group is mentioned as a substituent of the amino nitrogen of the amidine bond.
Furthermore, although patent document 3 is related with a herbicide, perfluoroalkylsulfonyl group is not mentioned at all as a nitrogen substituent of a carbonylimino group.

On the other hand, pest control agents having a trifluoromethylsulfonamide group are disclosed (for example, Patent Documents 4 to 6).
However, Patent Document 4 and Patent Document 5 relate to insecticides and acaricides, but do not have amidine bonds and merely disclose sulfonamide compounds.
Patent Document 6 discloses a compound used for an indoor dust mite control agent, but does not have an amidine bond, but merely discloses a sulfonamide compound.
On the other hand, an amidine compound having a trifluoromethylsulfonyl group has been disclosed (for example, Non-Patent Document 1). However, the disclosed compound is a compound in which a trifluoromethylsulfonyl group is contained in both nitrogen atoms of the amidine bond, and a compound in which a perfluoroalkylsulfonyl group is contained in one nitrogen atom is not mentioned at all. Furthermore, there is no description about the use.

JP 56-22704 A JP-A-5-1034 JP-A-6-293738 JP 57-156407 A Japanese Patent Publication No. 63-24483 Japanese Patent Laid-Open No. 10-218857 J. Chem. Soc., Perkin Trans. 2, 2002, 1950-1955

  Accordingly, an object of the present invention is to provide a novel trifluoromethylsulfonylamidine derivative having excellent insecticidal activity, acaricidal activity or herbicide activity.
