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