Uranium nitrides are attractive candidates for stoichiometric and catalytic N-transfer reactions, small molecule transformation,1,1 and for advanced nuclear fuels.5 to recent years an increasing number of molecular nitride compounds of uranium has been synthetized,2"4 However, the reactivity of bridging nitrides remains basically unexplored. The N-C bond formation reactions are key steps in the construction of value-added chemical compounds such as amino acids, pharmaceuticals or agroehemicals. Particularly desirable are the synthetic methods using cheap and available C_1 feedstock such as carbon dioxide or carbon monoxide, Ferf-butoxysiloxides were shown to be very effective ligands in supporting the reactivity of low valent / elements with small molecules due to their ability to stabilize heteromultimetaliic frameworks.
