3-Cyano-4-phenylpyrrol derivatives of the formula (I) …<IMAGE>… in which… Ar represents tri- to pentasubstituted phenyl and their use in pest-control agents and new intermediates. …<??>They can be prepared, for example, by reacting suitable substituted cinnamonitriles with suitable sulphonylmethyl isocyanides in the presence of a base. The substituted cinnamonitriles used can be prepared, for example, by reacting suitable substituted anilines with acrylonitrile, followed by dehydrohalogenation, or condensing suitable benzaldehydes with cyanoacetic acid with simultaneous decarboxylation. |
