The stable complex 2 (BF 4 ⊖salt) with HOCCH as a ligand was prepared from the edge‐protonated complex 1 and CO (55 bar) at room temperature. On silica gel, the HOC CH ligand undergoes oxidation to give a CCOOH ligand. When 2 is heated in the presence of CO, a rearrangement occurs, which formally involves a CO elimination (!) from the HOCCH ligand.
