Bulky substituents play important roles in controlling the reaction pathways or producing selected products. This work reports that the shift of metallafuran rings in a metallapentalenofuran complex can be promoted by the substituent effect via a reversible C−H bond reductive elimination and oxidative addition. The starting osmapentalyne, a so‐called 7‐carbon carbolong complex, was produced by the oxidation of a metallapentalenofuran with FeCl 3 . It was then allowed to react with nucleophiles, followed by a C−H activation, to give the aforementioned metallapentalenofuran complex. This work enriches the family of carbolong complexes and reveals a new strategy to promote, but not prevent reactions by the bulky substituents.
