Beyond its importance in nuclear industry the redox chemistry uranium is attracting increasinginterest because complexes of low-valent uranium can promote unusual reductive chemistrythrough unusual reaction pathways, including attractive examples of CO, CO2, N2, arenes andazides activation in mild condition. Due to the unique coordination and bonding properties ofuranium, its compounds could provide an attractive alternative to transition metals for thecatalytic transformation of small molecules. However, metal-based multi-electron processesremain uncommon in uranium chemistry especially in comparison with the d-block metals, thechemistry of low-valent uranium being dominated by single-electron transfers. In this context, thefirst aim of th...
