ABSTRACT:
The present invention provides a process for the manufacture of 2-aryl-5-(perfluoroalkyl)pyrrole-3-carbonitrile comprising the cycloaddition of 5-amino-4-aryl-2-perfluoroalkyl-1,3-oxazole and the appropriate 1,3-dipolarifile. The arylpyrrole-3-carbonitrile product and its derivatives are highly effective insecticidal, acaricidal and nematocidal agents.
