摘要：

(Figure Presented) Completing a circle of reactions: Reaction of a U V-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. © 2006 Wiley-VCH Verlag GmbH & Co.
