2-Arylazo-1-vinylpyrroles under the action of trifluoroacetic anhydride (CH2Cl2 or benzene, -5-0 °C, 1 h) form N-aryl-2,2,2-trifluoroacetamides along with conjugated (electroconducting and paramagnetic) polymers.

A convenient procedure for the preparation of aryl trifluoroacetamides from aryl amines is described that employs 2-4 M equiv of trifluoroacetic acid in refluxing xylene as a trifluoroacetylating agent. Addition of an amount of pyridine that is equimolar to the amount of trifluoroacetic acid present in the reaction mixture facilitates the trifluoroacetylation of rather basic arylamines.
