The reaction conditions and the nature of acyl chloride strongly influence the outcome of the primary polyfluoroalkanethioamides acylation. Preparation of NH-acetyl polyfluoroalkanethioamides was achieved conducting the reactions in acetonitrile at -20 degrees C in the presence of pyridine. The reactions of polyfluoroalkanethioamides with 5-hydroperfluoropentanoyl chloride are efficient for the synthesis of NH-acyl derivatives when they were carried out in the absence of a base under heating at 100 degrees C. The obtained NH-acyl polyfluoroalkanethioamides enter into cycloaddition reactions with 2,3-dimethylbutadiene at room temperature. (C) 2012 Elsevier B.V. All rights reserved.

Polyfluoroalkanethiocarboxylic acid amides react with aromatic aldehydes with the formation of bis(N-thioacyl)aminals. Treating the latter with acyl chlorides gives 2-aryl-substituted 4,5-bis(polyfluoroalkyl)imidazoles which constitutes a novel method of synthesizing these imidazole derivatives.
