    • The invention relates to a method, which is based on the oxidative ring opening of a compound with an oxindole structure, for producing substituted 2-(triazinylcarbonyl) sulfonanilides of formula (1-1) proceeding from an N-sulfonyl-substituted 3-triazinyl oxindole of formula (2-1), to the thus produced 2-(triazinylcarbonyl) sulfonanilides of formula (1-1), and to the use thereof as intermediate products for the synthesis of fine chemicals and active substances in the agricultural field. Furthermore, the invention relates to a multistage method for producing N-alkyl-N-[2-(1,3,5-triazin-2-ylcarbonyl)phenyl]alkansulfonamides of formula (4-1) proceeding from a 3-(alkylsulfanyl)-1,3-dihydro-2H-indol-2-on of formula (7-1), wherein the multistage method also has said oxidative opening as a sub-step, and to the 2-(triazinylcarbonyl) sulfonanilides of formula (1-1), said sulfonanilides being obtained by means of the oxidative ring opening and used as intermediates in the multistage method.
    • 本申请涉及一种方法,该方法是基于具有Oxindolstruktur的化合物的氧化开环,制备式(1-1)的取代的2-(Triazinylcarbonyl)sulfonaniliden的制备从N-3-sulfonylsubstituierten Triazinyloxindol启动式(2-1) 和如此制备的式(1-1)的2-(三嗪基 - 羰基)磺酰苯胺及其作为用于合成农业中的精细化学品和活性成分的中间体的用途。 此外,本发明涉及一种多级方法用于制备N-烷基-N- [2-(1,3,5-三嗪-2-基羰基)苯基]从3-(烷基硫基)启动式(4-1)的alkanesulfonamides -1,3-二氢-2H-吲哚-2-酮的式(7-1),其中,所述多阶段工艺包括如步骤的一部分的,所述式氧化​​开环和通过氧化开环得到的2-(Triazinylcarbonyl)磺酰苯胺 (1-1),它们在多阶段过程中用作中间体。
