Novel substituted thiophenecarboxamides of the formula (I), ##STR1## in which R represents hydrogen or alkyl, A represents doubly linked alkanediyl, Ar represents optionally substituted aryl and n represents a number 0 or 1, with the exception of the compounds 4,5-dibromo-thiophene-2-carboxylic acid N-(4-bromophenyl)-amide, 4,5-dibromo-thiophene-2-carboxylic acid N-(2,3-dichlorophenyl)-amide and 4,5-dibromo-thiophene-2-carboxylic acid N-[2-(3,4-dimethoxyphenyl)-ethyl]-amide, and their use for combating pests. The novel compounds are described by the formula (I) and they can be prepared by analogous processes, e.g. by reacting suitable thiophenecarbonyl halides with suitable amines.
化合物的名称为Novel substituted thiophenecarboxamides,化学式为(I):##STR1## 其中,R代表氢或烷基,A代表双键连接的烷基,Ar代表可选取代的芳基,n代表数字0或1。除了化合物4,5-二溴噻吩-2-羧酸N-(4-溴苯基)-酰胺、4,5-二溴噻吩-2-羧酸N-(2,3-二氯苯基)-酰胺和4,5-二溴噻吩-2-羧酸N-[2-(3,4-二甲氧基苯基)-乙基]-酰胺外,这些新化合物可用于防治害虫。化合物的制备方法可以通过类似的过程进行,例如通过反应适当的噻吩羧酰卤与适当的胺反应来制备。
