Creating an asymmetric environment at Au I is a challenge because of the linear coordination geometry of the ion. In their Communication on page 2912 ff., S. Handa and L. M. Slaughter report the highly enantioselective catalysis of a tandem addition/cycloisomerization reaction of alkynylbenzaldehydes by chiral gold carbene complexes containing weak metal–π interactions. These secondary interactions help to create an asymmetric pocket around the gold atom that is analogous to a baseball glove gripping a ball. (Picture by L. M. Slaughter and S. Ball.)
