Invited for the cover of this issue is the group of Oscar Navarro at the University of Sussex, UK. The cover image shows the stage in catalyst design when the choice of ancillary ligands to accompany the main “working” ligand is made. The use of triethylamine (TEA) as “throw‐away” ligand, unveiling the catalytically active L n Pd(0) species, leads to decreased catalyst loadings, and no inert atmosphere is required in Buchwald–Hartwig amination reactions.
