Synthesis and reactivity

The complex was first prepared by heating iron pentacarbonyl with the diene.[3]

Protonation of the title complex with hydrogen chloride give (allyl)Fe(CO)3Cl.[4]

Related compounds

Iron(0) complexes of conjugated dienes have been extensively studied. In the butadiene series, (η2-C4H6)Fe(CO)4 and (η2:η2-C4H6)(Fe(CO)4)2 have been crystallized.[5] Many related complexes are known for substituted butadienes and related species. The species (η4-isoprene)iron tricarbonyl is chiral.[6]
