    Abstract: The present invention relates to a process for preparing sulfamoyl halides of primary or secondary amines, comprising the following steps: i) reacting a primary or secondary amine A1 with at least equimolar amounts of SO 3 or an SO 3 source in the presence of at least equimolar amounts of a tertiary amine A2, based in each case on the amine A1, and ii) reacting the reaction mixture obtained in step i) with at least the amount of a phosphorus halide required by the stoichiometry; The invention further relates to a process for preparing sulfonic diamides, comprising the preparation of sulfamoyl halides by means of carrying out steps i) and ii) and subsequently reacting the sulfamoyl halide obtained with ammonia. The invention further relates to the use of this process for preparing active herbicidal ingredients having a sulfuric diamide structure. The invention further relates to novel sulfamoyl chlorides.

    Abstract: The present invention relates to piperazine compounds of the general formula I defined below and to their use as herbicides. Moreover, the invention relates to compositions for crop protection and to a method for controlling unwanted vegetation. In formula I, the variables have the following meanings: R1 is selected from the group consisting of halogen, cyano, nitro, Z—C(═O)—R11, phenyl and a 5- or 6-membered heterocyclic radical which has 1, 2, 3 or 4 heteroatoms selected from the group consisting of O, N and S as ring atoms, where phenyl and the heterocyclic radical are unsubstituted or may have 1, 2, 3 or 4 substituents R1a; Z is a covalent bond or a CH2 group; R11 is hydrogen, C1-C6-alkyl, C3-C6-cycloalkyl, C2-C6-alkenyl, C5-C6-cycloalkenyl, C2-C6-alkynyl and the like; R2 is hydrogen, halogen, nitro, cyano, C1-C4-alkyl, C1-C4-haloalkyl, C2-C4-alkenyl, C1-C4-alkoxy, C1-C4-haloalkoxy, benzyl or a group S(O)nR21 in which R21 is C1-C4-alkyl or C1-C4-haloalkyl and n is 0, 1 or 2; R3 is hydrogen or halogen; R4 is C1-C4-alkyl, C3-C4-alkenyl or C3-C4-alkynyl; R5 is hydrogen, C1-C4-alkyl, C3-C4-alkenyl, C3-C4-alkynyl or a group C(═O)R51 in which R51 is hydrogen, C1-C4-alkyl, C1-C4-haloalkyl, C1-C4-alkoxy or C1-C4-haloalkoxy; R6 is C1-C4-alkyl, C1-C4-hydroxyalkyl or C1-C4-haloalkyl; R7, R8 independently of one another are hydrogen, OH, C1-C4-alkoxy, C1-C4-haloalkyloxy, C1-C4-alkyl or C1-C4-haloalkyl; and R9, R10 independently of one another are selected from the group consisting of hydrogen, halogen, CN, NO2, C1-C4-alkyl, C1-C4-haloalkyl, C2-C4-alkenyl, C1-C4-alkoxy and C1-C4-haloalkoxy.
