title: Borderline metal-catalyzed carboarylation of alkynylarenes using N,O-acetals.
abstract: Borderline metal catalysts, Bi(OTf)(3) and Fe(OTf)(3), were proven to work as dual activators for alkynes and N,O-acetals via σ,π-chelation, which achieved a new carboarylation reaction of alkynylarenes with N,O-acetals.
