Lanthanide Bis(trifluoromethylsulfonyl)amides as Effective Reusable Catalysts for Catalytic Friedel–Crafts Acylation
Abstract
By using a catalytic amount of a lanthanide bis(trifluoromethylsulfonyl)amide, Ln(NFf2)3, the Friedel–Crafts acylation of substituted benzene proceeds smoothly under mild conditions and the catalysts are easily recovered from the reaction mixture.
