Playhouse NHC: Modulation of the π‐acceptor properties of ancillary carbene ligands allows great control over competing pathways in gold(I)‐catalyzed reactions. High selectivity can be achieved for the transformation of allenenes within a series of structurally similar but electronically different N‐heterocyclic carbenes (NHCs). The experimental results are supported by DFT calculations.
