η 4 ‐Vinylketene and/or metallacyclopentenone complexes can be considered key intermediates in the ruthenium‐ and rhodium‐catalyzed ring‐opening dimerization of cyclobutenones to give 2‐pyranones as well as in the rhodium‐catalyzed coupling reactions of cyclobutenones with 2‐norbornene (see scheme).
