using unactivated alkylhalides and a variety of arenes and heteroarenes is described. This ring-forming process is successful with a variety of unactivated primary and secondaryalkylhalides, including those with β-hydrogens. In contrast to standard polar or radical cyclizations of aromatic systems, electronic activation of the substrate is not required. The mild, catalytic reaction conditions are highly
