For the asymmetrical hydrogenation of substrates selected from prochiral olefins and compounds containing CO and/or CN groups, the olefin of interest here is contacted with a complex of a transition metal with an asymmetrical aminophosphine. The asymmetrical aminophosphine is selected from those of the formula PR@(NR<2>R<3>)3-x where R<1>, R<2> and R<3> are as defined in the claims. The catalytic system as a means for carrying out the abovementioned asymmetrical hydrogenation contains a complex obtained by a reaction starting from compounds of the formula (R<3>R<2>N)nX and a coordination compound of a metal from the transition series.
