The present invention relates to a crystalline form of 2-chloro-5-[3,6-dihydro-3-methyl-2,6-dioxo-4-(trifluoromethyl)-1-(2H)pyrimidinyl]-4-fluoro-N-[[methyl(1-methylethyl)-amino]sulfonyl]benzamide. The invention also relates to a process for the preparation of this crystalline form and to plant protection formulations which comprise this crystalline form of the phenyluracil.

Crystalline form of 2-chloro-5-[3,6-dihydro-3-methyl-2,6-dioxo-4-(trifluoromethyl)-1-(2H)-pyrimidinyl]-4-fluoro-N-[[methyl(1-methyl-ethyl)amino]sulfonyl]benzamide

The present invention relates to hydrates of 2-chloro-5-[3,6-dihydro-3-methyl-2,6-dioxo-4-(trifluoromethyl)-1-(2H)pyrimidinyl]-4-fluoro-N-[[methyl(1-methylethyl)amino]-sulfonyl]benzamide. The invention also relates to a process for the preparation of these hydrates and to plant protection formulations which comprise hydrates of the phenyluracil I.

Hydrates of 2-chloro-5-[3,6-dihydro-3-methyl-2,6-dioxo-4-(trifluoromethyl)-1-(2H)-pyrimidinyl]-4-fluoro-N-[[methyl(1-methylethyl)amino]sulfonyl]benzamide

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. 

Method for producing sulfonamides

The present invention relates to a process for preparing 3-phenyl(thio)uracils and -dithiouracils of the formula I where the variables are each as defined in the description, and also intermediates for their preparation.

Method for the production of 3-phenyl(thio)uracils and dithiouracils

The present invention relates to a process for preparing difluoromethyl-substituted pyrazol-4-ylcarboxylates of the formula I in which in which X is fluorine, chlorine or bromine, Rhas one of the meanings given above and Ris C-C-alkyl, C-C-cycloalkyl, C-C-alkenyl, benzyl or phenyl, is reacted with a silane compound of the general formula RSiClin which n is 1, 2 or 3 and the substituents Rare independently of one another selected from the group consisting of C-C-alkyl and phenyl and with a metal selected from the metals of groups 1, 2, 3, 4 and 12 of the Periodic Table of the Elements having a redox potential of less than &#x2212;0.7 V, based on a normal hydrogen electrode (at 25&#xb0; C. and 101.325 kPa); and
