Beautiful butterfly‐shaped chiral molecules and a host of other nanographenes can now be easily synthesized, as reported by W. A. Chalifoux and co‐workers in their Communication on page 14773 ff. The transformation takes place via a domino benzannulation reaction of conjugated diynes that is catalyzed by a mixture of InCl 3 and AgNTf 2 . The reaction is highly regioselective and gives the products in yields of up to 95 %.
