Owing to environmental and economic reasons, the transformation and valorization of abundant and readily available chemical feedstock such as CO and CO2 are very topical goals. Carbon monoxide is a C1 gas that is used in the industrial production of organic feedstock molecules such as methanol 2 and acetic acid. Synthesis gas (syn-gas: CO/H2) is converted into liquid hydrocarbons and oxygenates on industrial scales by using the Fischer-Tropsch (F-T) process. As the C≡O triple bond is one of the strongest chemical bonds (bond dissociation energy of 1075 kJ.mol -1 ), this process typically operates under harsh temperature and pressure conditions (200-350 °C, 20-45 bars) using heterogeneous transition metal catalysts (Fe, Co). The precise mechanism in the formation of F-T products is still under debate and, to gain more insight into the elementary steps involved, several organometallic complexes have been used as soluble models. Similarly, recent advances in transition-metal-free F-T chemistry have been reported, describing formation of growing carbon chains. 8
