The present invention relates to a process for preparing sulfuric diamides of the general formula IRRN&#x2014;S(O)&#x2014;NH&#x2003;&#x2003;(I)in which Rand Rare each independently a primary alkyl radical having from 1 to 8 carbon atoms, a secondary alkyl radical having from 3 to 8 carbon atoms or a cycloalkyl radical having from 5 to 8 carbon atoms, or, together with the nitrogen atom, form a 5- to 8-membered, saturated nitrogen heterocycle which, as well as the nitrogen atom, may have a further heteroatom selected from O and S as a ring member, where the nitrogen heterocycle is unsubstituted or may have 1, 2, 3 or 4 alkyl groups having in each case from 1 to 4 carbon atoms as substituents. The process comprises the following steps:

Methods for producing sulfonic acid diamides

The present invention relates to novel trifluoromethoxyphenyl-substituted tetramic acid derivatives of the formula (I), in whichJ, X, Y, A, B, D and G have the meanings given above,to a number of processes for their preparation, and to their use as pesticides and/or herbicides. The invention further provides selective herbicidal compositions which comprise, firstly, trifluoromethoxyphenyl-substituted tetramic acid derivatives and, secondly, a crop plant compatibility-improving compound. The invention further relates to the boosting of the action of crop protection compositions comprising compounds of the formula (I) through the additions of ammonium salts or phosphonium salts and optionally penetrants.

Trifluromethoxyphenyl-substituted tetramic acid derivatives pesticides and/or herbicides

The invention relates to methods for producing sulfonamides of formula I, wherein the variables have the designations cited in the description, by reacting m-nitro-benzoic acid chlorides of formula II with aminosulfons of formula III, under the influence of B equivalents of base IV. Said method is characterized in that, during step a) the aminosulfon of formula III is reacted with B1 equivalents of base IV, and during step b), the reaction mixture resulting from step a) is reacted with m-nitro-benzoic acid chlorides of formula II and B2 equivalents of base IV; B, B1 and B2 having the designations cited in the description.
