We report herein an unprecedented protocol for aminotrifluoromethylation of alkenes. With Cu(OTf)2 as the catalyst, the reaction of alkenes, (bpy)Zn(CF3)2 and N-fluorobis(benzenesulfonyl)imide (NFSI) at room temperature provides the corresponding aminotrifluoromethylation products in satisfactory yields with high regioselectivity opposite to those driven by CF3 radical addition. The method exhibits
