    • The invention relates to a method for the production of sulphamic acid halogenides of primary or secondary amines, comprising the following steps: i) reaction of a primary or secondary amine A1 with at least equimolar amounts of SO3 or an S03 source in the presence of at least equimolar amounts of a tertiary amine A2, respectively in relation to amine A1, and ii) reaction of the reaction mixture obtained in step i) with at least the stochiometrically required amount of phosphorus halogenide. The invention also relates to a method for the production of sulphamic acid diamides, comprising the production of sulphamic acid halogenides by carrying out steps i) and ii) and by subsequently reacting the sulphamic acid halogenides thus obtained with ammonia.The invention further relates to the use of said method in the production of herbicidal active ingredients with a sulphodiamide structure. The invention also relates to novel sulphamic acid chlorides.
    • 本发明涉及生产伯胺或仲胺的氨基磺酰氯的方法,其包括以下步骤:i)伯或仲胺A1与至少等摩尔量的SO 3或SO 3源在 分别相对于胺A1为最少等摩尔量的叔胺A2,和ii)使步骤i)中获得的反应混合物与至少化学计量需要量的卤化磷反应。 本发明还涉及生产氨基磺酸二酰胺的方法,该方法包括通过进行步骤i)和ii)产生氨基磺酰卤,并随后使由此获得的氨基磺酸酰卤与氨反应。本发明进一步涉及 所述方法在制备具有磺基二酰胺结构的除草活性成分中的用途。 本发明还涉及新型氨基磺酰氯。
