5-CHLORO-1,3,4-THIADIAZOL-2-YLOXYACETAMIDE

1. 5-Chloro-1,3,4-thiadiazol-2-yloxy-acetamides of the general formula (I) see diagramm : EP0192117,P12,F1 in which R**1 and R**2 independently of one another represent straight-chain or branched alkyl with 1 to 8 carbon atoms, straight-chain or branched alkenyl and alkinyl each with 2 to 8 carbon atoms, cycloalkyl or cycloalkenyl, each with 3 to 7 carbon atoms, which optionally have one or more identical or different substituents (possible substituents being, in particular, alkyl radicals with 1 to 4 carbon atoms), or represent alkoxy, alkoxyalkyleneoxy or alkoxyalkyl, each of which is straight-chain or branched and has 1 to 8 carbon atoms in the individual alkyl or alkylene moieties, or represent halogenoalkyl with 1 to 8 carbon atoms and 1 to 5 halogen atoms or represent aralkyl with 6 to 10 carbon atoms in the aryl moiety and 1 to 2 carbon atoms in the alkyl moiety, as well as aryl with 6 to 10 carbon atoms which optionally has one or more identical or different substituents (possible substituents being : halogen, straight-chain or branched alkyl, alkoxy or alkylthio each with 1 to 4 carbon atoms, halogenoalkyl, halogenoalkoxy and halogenoalkylthio each with 1 to 2 carbon atoms and 1 to 5 halogen atoms, as well as nitro), or R**1 and R**2 together with the nitrogen atom to which they are bonded represent a saturated or unsaturated 5- to 7-membered heterocyclic ring which optionally has one or more identical or different substituents (possible substituents being : straight-chain or branched alkyl with 1 to 6 carbon atoms, also in the form of a fused ring system, aryl with 6 to 10 carbon atoms, also in the form of a fused ring system, or dioxyalkylene with 2 to 3 carbon atoms).
