As a result of the interaction of substituted aminobenzoic acids and dichloromaleic anhydride in glacial acetic acid, various N-substituted imides of dichloromaleic acid have been obtained. Based on the diene synthesis of cyclopentadiene and N-substituted imides of dichloromaleic acid, N-(orthometa- and para-carboxyphenyl)imides of 2,3-dichlorocyclo-[2.2.1]hept-5-ene-2,3-dicarboxylic acid have been syn­thesized. The obtained imides have been tested as a potential effective complex biologically active drug. The results of multiple tests have demonstrated that these compounds possess, simultangonsly, high fungicidal and bactericidal activity against cotton verticillus wilt. So, for a concentration of 0.1%, the obtained compounds  almost completely destroy the fungus verticillum dahliae, as well as thionic iron-oxidizing and sulfate-reducing aerobic bacteria VKM V-458 and VKM V-1388
