Synthesis and Ligand Properties of Stable Five-Membered-Ring Allenes Containing Only Second-Row Elements

Push–push substitution patterns render allenes so flexible that the usually linear CCC fragment can be accommodated in a five‐membered ring composed of only nitrogen and carbon atoms (see structure; C black, N blue, O red). These cyclic allenes appear to be strong donor η1 ligands for alkali and t...

Summary:Push–push substitution patterns render allenes so flexible that the usually linear CCC fragment can be accommodated in a five‐membered ring composed of only nitrogen and carbon atoms (see structure; C black, N blue, O red). These cyclic allenes appear to be strong donor η1 ligands for alkali and transition metals.
