Abstract A mild, convenient, and step-economical intramolecular aminotrifluoromethylation of unactivated alkenes with a variety of electronically distinct, nitrogen-based nucleophiles in the presence of a simple copper salt catalyst, in the absence of extra ligands, is described. Many different nitrogen-based nucleophiles (eg, basic primary aliphatic and aromatic amines, sulfonamides, carbamates, and ureas) can be employed in this new ...
