trans- or cis-2,3-Bis(hydroxymethyl)methylenecyclopropanes react with [Fe2(CO)9] to produce tricarbonyl-η4-[3-methylene-endo-4-vinyldihydrofuran-2(3H)-one]iron(0) and tetracarbonyl-η2-[3-methylene-exo-4-vinyldihydro-furan-2(3H)-one]iron(0). The structural identities of these two complexes have been established by the analysis of single-crystal X-ray data recorded on a four-circle diffractometer.
