Imido metal complexes of the late 3d-metals are of substantial importance for the direct amination of unfunctionalised C–H bonds. Due to the high reactivity of such imido complexes, the factors that drive and determine their reactivity are only ill understood. This project aims at the Isolation of low-coordinate imido metal complexes of iron to nickel in high spin- and formal oxidation states. By this we wish to evoke pronounced imidyl and nitrene character of these compounds. In due process the reactivity of these compounds in terms of C–H bond as well as nucleophilic and electrophilic substrate activation in the relation to the oxidation state is to be assessed. Overall this serves for a better understanding of the imido metal bond itself, which is necessary for any rational design of a catalytic application.
