1,5‐cyclooctadiene (COD) and iodide ion has been demonstrated as robust, efficient, recyclable solid molecular catalyst for N‐formylation of diverse primary and secondary amines with CO2 and H2 under mild reaction conditions. Remarkably, in the case of N,N‐dimethylformamide production, even at 0.1 mol % catalyst loading under solvent‐free conditions, the solid catalyst can be readily recovered by simply
