Sequential Friedel–Crafts-Type α-Amidoalkylation/Intramolecular Hydroarylation: Distinct Advantage of Combined Tf2NH/Cationic LAu(I) as a Consecutive or Binary Bicatalytic System

The combined use of Tf2NH and L(Au)+X– as a dual or binary catalytic system clearly improves the efficiency and enlarges the scope of the tandem intermolecular Friedel–Crafts α-amidoalkylation/intramolecular hydroarylation sequence, compared to an “all gold” multicatalysis approach.
