WebThe [HRh(CO)(TPPTS)3] precursor, where TPPTS is the water-soluble P(m-C6H4SO3Na)3 ligand, has opened a large area for the Supported-Aqueous-Phase (SAP) catalysed functionalisation of heavy substrates. We investigated several ways to increase the efficiency of heavy alkenes hydroformylation by [Rh2(μ-StBu)2(CO)2(TPPTS)2]. Web15 apr. 2024 · The use of phosphites as ligands instead of phosphines also led to a higher n/iso ratio.The percentage of linearity obtained for PPh 3 and P(OPh) 3 is very similar at low ligand concentrations. However, at higher ligand concentrations, phosphites give a better n/iso ratio of products. The electronic and steric effects of the substituents on the …
