In ionic liquids [Bmim][PF6] or [Bmim][BF4], a highly regioselective
N-substitution of pyrrole with alkyl halides, sulfonyl chlorides, and benzoyl
chloride gave substituted pyrroles in excellent yields. Michael addition of
pyrrole with electrophilic olefins was completed in a highly regioselective
manner to afford N-alkylpyrroles.
