A catalytic system obtained by in situ mixing [RuCl2(benzene)]2 and (S)-BINAP has been tested in the asymmetric hydrogenation of various substrates. The best results have been obtained working in methanol: excellent optical purities were achieved in the reduction of substrates such as tiglic acid (83%), geraniol (97%) and methyl 3-oxobutanoate (95%). Some investigations on the nature of the catalyst have been carried out.
