Pushed to the limit : Pushing CC π bonds to the breaking point by using a push–push substitution pattern forces allenes to bend (see structure; C light blue, N dark blue). An acyclic allene featuring a CCC bond angle of 134.8° has been isolated in which the typically sp‐hybridized central carbon atom approaches a configuration that has two lone pairs of electrons, and acts as a very strong η 1 ‐donor ligand for transition metals.
