ABSTRACT:

The present invention relates to novel aryl-substituted S(O)
m
cycles (&agr;-phenyl-&bgr;-keto sulphones), to a plurality of processes for their preparation and to their use in agriculture, for example as crop protection agents (for example as fungicides, herbicides and insecticides).
4-Amino-5-phenyl-3-ethyl-2-methyl-2,3-dihydroisothiazole 1,1-dioxide (J. L. Marco et al., Tetrahedron Letters 39, 4123 (1998)), 4-amino-5-phenyl-3,3-dimethyl-2-benzyl-2,3-dihydroisothiazole 1,1-dioxide and 4-amino-5-phenyl-3,3-dimethyl-2-(3-chloro-benzyl)-2,3-dihydroisothiazole 1,1-dioxide (S. T. Ingate, et al., Tetrahedron 53, 17795 (1997)) are known from the literature. Also known are 2-methyl-5-phenyl-isothiazolidin-4-one 1,1-dioxide, 2,3-dimethyl-5-phenyl-isothiazolidin-4-one 1,1-dioxide and 5-phenyl-2,3,3-trimethyl-isothiazolidin-4-one 1,1-dioxide (H.-D. Stachel, G. Drasch, Archiv Pharm. 318, 304 (1985)). Use of these compounds as crop protection agents or pesticides has hitherto not been disclosed.
Furthermore known are 3-phenyl-1,2-oxathiolan-4-one 2,2-dioxide, 5-methyl-3-phenyl-1,2-oxathiolan-4-one 2,2-dioxide, 5,5-dimethyl-3-phenyl-1,2-oxathiolan-4-one 2,2-dioxide (H. D. Stachel, G. Drasch, Archiv Pharm. 318, 304 (1985)), 5-amino-5,5-dimethyl-3-phenyl-1,2-oxathiolane 2,2-dioxide and 4-amino-5-methyl-3-phenyl-5-phenylmethyl-1,2-oxathiolane 2,2-dioxide (S. T. Ingate et al., Tetrahedron 53, 17795 (1997)). Use of these compounds as crop protection agents or pesticides has hitherto not been disclosed.
2-Arylbenzo[b]thiophen-3(2H)-one 1,1-dioxides have been disclosed for use as anti-inflammatory agents and anticoagulants (J. G. Lombardino, E. H. Wiseman, J. Med. Chem., 13, 206 (1970)). Also known is 2-phenyl-3-keto-tetrahydrothiophene 1,1-dioxide (A. Abdel-Wahab et al., Phosphorus, Sulfur and Silicon, 59, 149 (1991)). Furthermore known are 2-phenylbenzo[b]thiophene-3-amine, 2-phenylbenzo[b]-thiophene-3-amine 1-oxide and 2-phenylbenzo[b]thiophene-3-amine 1,1-dioxide (J. R. Beck, J. Heterocyclic Chem. 15, 513 (1978)). Likewise, a use of these compounds as crop protection agents or pesticides has hitherto not been disclosed.
This invention, accordingly, provides aryl-substituted S(O)

Depending inter alia on the nature of the substituents, the compounds of the formula (I) can be present as geometric and/or optical isomers or isomer mixtures of different composition which, if appropriate, can be separated in a customary manner. The present invention provides both the pure isomers and the isomer mixtures, their preparation and use and the compositions comprising them. However, hereinbelow, for the sake of simplicity, compounds of the formula (I) are always referred to, although this may mean both the pure
