A general route to μ‐methylene complexes (dimetallacyclopropanes) is the addition of carbenes (generated from diazoalkanes) to species with reactive metal‐metal bonds. For example, (Me 5 C 5 ) 2 Rh 2 (CO) 2 reacts with carbenes RR′C: depending on the spatial requirements of the substituents R and R′ with elimination of CO to give (1) or with intramolecular opening of the carbonyl bridge to give (2) .
