ALKYL SULPHINYL AND ALKYL SULPHONYL-1,2,4-THIADIAZOLYLOXY ACETAMIDES AND THEIR USE AS HERBICIDES

摘要

The invention relates to novel alkyl sulphinyl and alkyl sulphonyl-1,2,4-thiadiazolyloxy acetamides of formula (I) in which n is the numbers 1 or 2, R<1> is hydrogen or possibly substituted alkyl, alkenyl, alkinyl or aralkyl, R<2> is possibly substituted alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkenyl, aralkyl, aryl, alkoxy, alkenyloxy or alkinyloxy, or R<1> and R<2> together with the nitrogen atom to which they are bound form a possibly substituted, saturated or unsaturated nitrogen heterocycle which may contain other hetero atoms and to which a benzo group may be annellated, and R<3> is possibly substituted alkyl, aryl or arylalkyl (wherein certain prior art individual compounds are excluded), and also processes and novel intermediate products for producing the novel compounds and their use as herbicides.
