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].
