5-Halogenoalkyl-1,3,4-thiadiazol-2-yloxyacetamides of the formula ##STR1## in which R.sup.1 is halogenoalkyl, with the exception of trifluoromethyl, and R.sup.2 and R.sup.3 each independently is hydrogen, alkyl, alkenyl, alkinyl, in each case optionally substituted cycloalkyl or cycloalkenyl, halogenoalkyl, alkoxyalkyl, alkoxyalkylenoxy, alkoxy, aralkyl or optionally substituted aryl, or R.sup.2 and R.sup.3, together with the nitrogen atom to which they are bonded, form an optionally substituted heterocyclic radical which can contain further hetero-atoms, which possess herbicidal and fungicidal activity. The intermediates 5-chlorodifluoromethyl- and 5-dichlorofluoromethyl-2-chloro-1,3,4-thiadiazole are also new.
公式为##STR1##的5-卤代烷基-1,3,4-噻二唑-2-氧乙酰胺,其中R.sup.1是卤代烷基,三氟甲基除外,R.sup.2和R.sup.3各自独立地是氢、烷基、烯基、炔基、在每种情况下均可选择取代的环烷基或环烯基、卤代烷基、烷氧基烷氧基氧、烷氧基、芳基烷基或可选取代的芳基,或R.sup.2和R.sup.3与它们所连接的氮原子一起形成可选择取代的杂环基团,该杂环基团可以含有进一步的杂原子,具有除草和杀真菌活性。中间体5-氯二氟甲基-和5-二氯氟甲基-2-氯-1,3,4-噻二唑也是新的。
