Extra! Extra! Read all about it! Para(normal) metalation of a pendant arene present on an N‐heterocyclic carbene has been observed. In their Communication on page 14075 ff., R. E. Mulvey et al. show that reaction of the NHC with a pre‐inverse‐crown template base induces three metal–ligand contacts: a normal NaC dative bond, an abnormal NaC bond, and a “paranormal” MgC bond at the para position of the pendant arene.
