involves the use of a preformed, bench‐stable Pd–N‐heterocyclic carbene pre‐catalyst bearing IHept as an ancillary ligand, and allows the coupling of various functionalized coupling partners at very lowcatalystloading. Careful choice of the solvent/base system was crucial to obtain optimum catalyst performance. The pre‐catalyst was also successfully tested in the synthesis of an industrially relevant
