    摘要: 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 andn 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.
