Multiple‐Bond Metathesis Mediated by Sterically Pressured Uranium Complexes

Abstract

Completing a circle of reactions: Reaction of a UV–imido complex (2) with a π acid (e.g., CH3NC) affords a UIV–heterocumulene complex (3), which reacts with an alkyl halide to yield the free carbodiimide and corresponding UIV–halide complex (4). Reduction of complex 4 recovers 1, thereby closing a cycle in which a nitrogen atom is transferred from a UV–imido complex to a π acid by multiple-bond metathesis.
