  Copper(I)-Catalyzed Halogenation and Acyloxylation of Aryl Triflates through a Copper(I)/Copper(III) Catalytic Cycle

  摘要：

  Catalyzed by CuOTf under very mild conditions, aryl triflates which are embedded in the azacalix[1]-arene[3]pyridine macrocycle underwent coupling reactions with metal halides and acetates to afford respectively halogenated and acyloxylated arene products in moderate to excellent yields. The unprecedented CuOTf-catalyzed transformations of aryl triflates proceeded through an oxidative addition of intramolecularly chelated Cu(I) into the C-O bond of aryl triflates to form arylcopper(III) intermediates which underwent anion exchange and reductive elimination reactions with nucleophiles to yield functionalized macrocyclic products.
