Phosphine-metal complexes transfer hydrogenation

Pioneering studies of the use of water soluble noble metal complexes of sulfonated phosphines as catalysts in aqueous biphasic systems were performed in the early 1970s, by Joo and Beck in Hungary and Kuntz at Rhone-Poulenc in France. Joo and Beck studied catalytic hydrogenations and transfer hydrogenations using Rh or Ru complexes of tppms [24]. Kuntz, on the other hand, pre-... [Pg.301]

The catalysts for transfer hydrogenations are usually late transition metal complexes with tertiary phosphine ligands or bidentate nitrogen ligands, and the donors are usually organic compounds whose oxidation potential is sufficiently low to tolerate hydrogen transfer under mild conditions. Suitable donors are secondary alcohols such isopropanol. This alcohol is the most convenient since it is stable, non-toxic, environmentally friendly, easy to handle (bp 82°C), inexpensive and dissolves many organic compounds. [Pg.108]
