| titleOfInvention | Processes for preparing sulfonylureas |
| abstract | A process for preparing compounds of the formula O O R3 N R1 X S N C N Y N O R6 R5 R4 (I) or salts thereof in which X is oxygen, -O- NR2- or -SO2-NR2, Y is nitrogen or CH, R1 is (C1-C6) alkyl, (C2-C6) alkenyl or (C2-C6) alkynyl, where each of the latter three radicals, independently of each other, is unsubstituted or substituted by one or more radicals selected from the group comprising halogen, (C1-C4) alkoxy and £(C1-C4) alkoxy| -carbonyl, or in the case where X = oxygen, also phenyl, which is unsubstituted or substituted by one or more radicals selected from the group comprising halogen, nitro, (C1-C4) alkyl, (C1-C4) haloalkyl, (C1-C4) alkoxy, (C1-C4) haloalkoxy and £(C1-C4) - alkoxyl| -carbonyl, R2 is hydrogen, (C1-C6) alkyl, (C2-C6) alkenyl, (C2-C6) - alkynyl or (C3-C6) cycloalkyl, R3 and R4, independently of each other, are hydrogen, (C1-C4) alkyl or (C1-C4) alkoxy, where each of the latter two radicals is unsubstituted or substituted by one or more radicals selected from the group comprising halogen, alkoxy and alkylthio, or is halogen, (C1-C4) alkylthio, (C1-C4) alkylamino or di (C1-C4) alkyl| - amino and R5 is hydrogen or (C1-C4) alkyl and R6 is hydrogen, wherein compounds of the formula R1 X R7 in which R1 and X are defined as in formula (I) and R7 is hydrogen, a quaternary ammonium ion or one equivalent of a singly, doubly or multiply charged metal cation, are reacted with compounds of the formulae R8-OCN SO2C12 R3 N HN Y N R4 R5 in which R3, R4, R5, X and Y are defined as in formula I and R8 is hydrogen, a quaternary ammonium ion or one equivalent of a singly, doubly or multiply charged metal cation. |
