Synthesis of Aza-Bridged Tetraphosphine Ligands for a Dirhodium Hydroformylation Catalyst
A novel tetraphosphine ligand rac-et,ph-P4 (et,ph-P4 = PEt2CH2CH2(Ph)PCH2P(Ph)CH2CH2PEt2) is used for the formation of a highly active and regioselective hydroformylation catalyst. The active catalytic species, Rh2H2(Ý-CO)2(et,ph-P4)]2+, is formed in situ under H2/CO pressure. This is one of the mo...
