Article abstract of DOI:10.1016/S0040-4039(00)78448-6

N-Unsubstituted 3,4-difluoropyrrole is synthesized via a thermal <2+3> cycloaddition reaction of a N-tert-butyl 2-alkoxycarbonyl aziridine and chlorotrifluoroethylene.Dealkylation of an intermediate N-tert-butylpyrrole is obtained with trifluoromethanesulfonic acid.
