The catalyst precursor preparedin situ from rhodium dimer [Rh(cod)Cl]2 and a new water-soluble phosphine Ph2PCH2CH2CONHC(CH3)2CH2SO3H (in Li+ salt form) has been found to act as an effective olefin hydrogenation catalyst. Catalytic hydrogenation reactions have been tested in either two phase: aqueous catalyst/insoluble olefin or methanolic catalyst/olefin systems. The observed reaction rates were higher for terminal than for internal olefins. 1-Hexene in methanolic solution has been hydrogenated with a turnover frequency of about 8000 h−1. This system has also been applied in the form of a supported aqueous phase catalyst.

- In aqueous solutions containing Rh(III) ions and a water soluble phosphine the latter is catalytically oxidized with water (see ref. 9). A similar process was also observed for Rh(I). This process is highly dependent on the solution parameters. A detailed study of the reaction between Rh(I) or Rh(III) and the potentially chelating P−O phosphine ligand in aqueous media will be reported elsewhere.
