Cover Picture: Cleavage of Carbodicarbenes with N2O for Accessing Stable Diazoalkenes: Two‐Fold Ligand Exchange at a C(0)‐Atom (Angew. Chem. Int. Ed. 3/2025)

Puzzling of ligands at C(0): In their Research Article (e202415228), Max M. Hansmann et al. demonstrate a new strategy to afford stable diazoalkenes by cleavage of a carbophosphinocarbene and carbodicarbenes with N2O. The follow‐up N2/NHC exchange allows easy access to novel carbodicarbenes or cumulenic compounds. The combination of exchange reactions overall allows to “puzzle” the fragments at a C(0) atom.
