The reactions of N-benzoyl- and N-acetyl-1-chloro-2,2,2-trifluoroethylamines with various carbon-nucleophiles gave the corresponding 1-substituted N-acyl-2,2,2-trifluoroethylamines in good yields and the efficient reactivity was applied on the synthesis of 2-acylamino-2-trifluoromethylethanol derivative.

There is provided a process for the preparation of 2-aryl-5-(perfluoroalkyl)pyrrole compounds from N-[1-chloro-1-(perfluoroalkyl)methyl]arylimidoyl chloride compounds. The 2-aryl-5-(perfluoroalkyl)pyrrole compounds are useful for the control of insect and acarid pests, and may also be used to prepare other pesticidal arylpyrrole compounds.
In addition, the present invention provides compounds which are useful as intermediates in the preparation of arylpyrrole compounds.
