Resum

A RhIII complex featuring an electron-deficient η5-cyclopentadienyl ligand catalyzed an unusual annulation between alkynes and 2-alkenyl anilides to form synthetically appealing 2-substituted indolines. Formally, the process can be viewed as an allylic amination with concomitant hydrocarbonation of the alkyne. Mechanistic experiments indicate that this transformation involves an unusual rhodium migration with a concomitant 1,5-H shift.
