There is provided a single step procedure to prepare 2-aryl-5-perfluoroalkylpyrrole derivatives directly from the perfluoroacetylated Strecker reaction product. Said pyrrole derivatives are insecticidal and also useful as precursors to other insecticidal arylpyrrole compounds. Further provided are amide nitrile intermediates, useful in the preparation of insecticidal arylpyrrole compounds.
There are provided ammonium oxazole intermediates of formula I and amino oxazolium intermediates of formula II, useful in the manufacture of insecticidal arylpyrrole compounds. ##STR1##
