Gold(III) Chloride/Silver Triflate: A Highly Efficient Catalyst for Ring‐Opening Reaction of Aziridines with Electron‐Rich Arenes.

Gold(III) chloride/silver triflate was found to a highly efficient catalyst in the ring-opening of aziridines with electron-rich arenes and the desired s-arylamines were afforded in good to excellent yields under mild reaction conditions.
