The migratory insertion reaction of a (cyclopentadienyl)methyliron dicarbonyl 2 containing the chiral (binaphthyldiyldimethylene)cyclopentadienyl ligand 1 in the presence of triphenylphosphine can proceed with modest diastereoselectivity. The resulting acyliron complexes 5 are separable and are configurationally stable under oxidative conditions.
