摘要

'' processes for the preparation of a compound of 2 - aril - 5 - (perfluoro alkyl) - pyrrole and a pyrrole aryl compound, and chloride compound n - (perfluoro alkyl methyl) - aril - imidou00ecla ''.It is provided a process for the preparation of the compounds of 2 - aril - 5 - (perfluoro alkyl) - pyrrole from chloride compounds n - (perfluoro alkyl methyl) - - imidou00edla aril.The compounds of 2 - aril - 5 - (perfluoro alkyl) - pyrrole are useful for the control of insect and mite pests.And can also be used to prepare other pesticides of aryl pyrrole type compounds.In addition, the present invention provides chloride compounds n - (perfluoro alkyl methyl) - aril - imidou00edla which are useful as intermediates in the preparation of aryl pyrrole compounds.
