Multiple ligand transfer to planar-chiral cyclopentadienylruthenium complexes inducing metal-centered chirality

Abstract

Multiple ligand transfer reaction between planar-chiral cyclopentadienylruthenium complexes [Cp′Ru(AN)₃][PF₆] [(Cp′ = 1-(CO₂Et)-2-Me-4-RC₅H₂, R = Me, Ph, Bu^t, AN = acetonitrile] and iron complexes CpFe(CO)(L)X (L = PMe₃, PPh₃; X = I, Br) results in formation of metal-centered chiral ruthenium complexes Cp′Ru(CO)(L)X with a diastereoselectivity (de) up to 68%.
