The title reaction has been studied using the in situ catalysts prepared from 2, 2 or Rh(COD)(acac) and a series of mono- and diphosphines.The use of (+)-N-acetylphenylalanine as a chiral carboxylato ligand gave catalytic systems with low asymetric efficiency ( optical yields from 5 to 10percent).Kinetics of the hydrogenation catalysed by 2 + (C6H5)2P(CH2)4P(C6H5)2 or P(n-C4H9)3 ( Rh : P mol.ratio = 1:2 ) is reported.
