A novel d0–d8 heterobimetallic complex obtained by co-ordination of a zirconium(IV) diphosphine to dinuclear rhodium(I) moiety leading to a hydroformylation-active species
Abstract
Addition of the ziroconium (IV)[(η5-C5H5)2Zr(CH2PPh2)2], to the µ-thiolato dirhodium(I) complex, [Ru2(µ-SBut)2(CO)4] result in the novel bimetallic species [Rh2(µ-SBut)2{µ2-[Ph2PCH2]2Zr(η5-C5H5)2}(CO)2] which is a better catalyst for low pressure hydroformylation of hex-1-ene than the analogous compound [Rh2(µ-SBut)2{µ2-Ph2P[CH2]4PPh2}(CO)2]; the special role of the electronic properties induced by zirconium is discussed.
