Abstract

The reaction of diphenyldiazomethane with [((ArO) tacn)U] (1) results in an η-bound diphenyldiazomethane uranium complex. This complex exhibits unusual electronic properties as a charge-separated species with a radical anionic open-shell ligand, [((ArO)tacn)U(η- NNCPh)] (2). Treating PhCN with a uranium complex that contains a sterically more demanding adamantane functionalized ligand, [((ArO)tacn)U] (3) results in an unprecedented C-H activation and nitrogen insertion to produce a five-membered heterocyclic indazole complex, [((ArO)tacn)U (η-3-phen(Ind))] (5). X-ray crystallography and spectroscopic characterization of these two compounds show that the [(( ArO)tacn)U(η-NNCPh )] compound is a U(IV) complex with a radical anionic ligand, whereas [((ArO)tacn)U(η-3- phen(Ind))] is a U(IV) f species with a closed-shell ligand. © 2008 American Chemical Society.
