Abstract

A series of previously unknown trifluoroacetyl derivatives of pyrroles were obtained with high yields by the reaction of pyrroles, including N-vinyl-substituted pyrroles, with trifluoroacetic anhydride in the presence of pyridine at room temperature. The solvent and the substituents at the α and Β positions of the pyrrole ring do not affect the direction of electrophilic substitution.
