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 β-arylamines were afforded in good to excellent yields under mild reaction conditions.
Aziridines react smoothly with arenes in the presence of a catalytic amount of indium triflate at ambient temperature to afford the corresponding P-aryl amine derivatives in excellent yields with high regioselectivity. (C) 2001 Elsevier Science Ltd. All rights reserved.

Iron(III) chloride was discovered highly effective as catalyst in the Friedel-Crafts reactions of electron-rich arenes with imines or aziridines. It was found that reactions of imines were highly substrate-dependent, which generated mono- or double-addition products, while arenes reacted with aziridines regioselectively leading to the formation of desired ring-opening products in 2 min with moderate to good yields.
