Abstract: The invention relates to a process for preparing thioethers of the formula XIX: (see formula XIX) in which the substituents are as defined below: Rx is halogen, carboxamide, N-alkyul-carboxamide, N,N-dialkylcarboxamide, phenyl, C1-C6-alkyl, C1-C6-alkoxy or C1-C6-alkylthio, m is a number from 0 to 5, and R2 is C1-C6-alkyl, which comprises reacting an aniline of the formula XX: (see formula XX) in which Rx and m are defined as above with a dialkyl disulfide of the formula VII: R2-S-S-R2 VII in which R2 is defined as above, and with an organic nitrite R-ONO in the presence of a catalyst.

Abstract: The invention relates to a process for preparing thioethers of the formula XIX: (see formula XIX) Rx is hydrogen, alkyl, haloalkyl, halogen, cyano, nitro, alkoxy, haloalkoxy, alkylthio or an unsubstituted, substituted, saturated, unsaturated or partially unsaturated heterocycle having one, two or three oxygen, sulphur or nitrogen atoms; m is a number from 0 to 5, and R2 is C1 -C6-alkyl, which comprises reacting an aniline of the formula XX: (see formula XX) with a dialkyl disulfide of the formula VII: R2-S-S-R2 VII and with C1-C6-alkyl nitrite in the presence of copper powder or elemental cooper at temperatures in the range of from 40 to 150°C. The above compounds of the formula XIX are useful intermediates for preparing isoxazoline-3-yl-acylbenzenes that have herbicidal activity.
