Abstract
The ligands (S)-N-(diphenylphosphino)-2-diphenylphosphinoxymethylpyrrolidine, (S)-prolophos, and (S)-1-diphenylphosphinoxy-2-N-diphenylphosphinoaminobutane, (S)-butaphos, have been prepared. The Rh(I) complexes of these phosphines act as efficient homogenous hydrogenation catalysts at ambient temperature and pressure for A-N-acetaminoacrylic acid and itaconic acid.
