Not so innocent : Sterically tuneable dithiocarboxylate ligands derived from N‐heterocyclic carbenes act as excellent bidentate chelates for ruthenium(II) σ‐alkenyl complexes. However, the most sterically demanding member of the ligand family causes a fascinating and unexpected rearrangement to occur (see figure; ICy=1,3‐dicylohexylimidazolium, IDip=1,3‐bis(2,6‐diisopropylphenyl)imidazolium).
