Bent allenes : Theoretical calculations show that extremely bent allenes, cyclic or acyclic, adopt a ground state that only bears a formal relationship to classical allenes. Consequently, five‐membered ring allenes favor a carbene‐like electronic structure and formally contain a trivalent carbon(II) center (see figure).
