method for the asymmetric hydrogenation of alkenes prochirale or racemic or co and / or cn groups containing compounds.process for the preparation of asymmetric aminofosfinen and method for the preparation of a complex with catalytic activity for the hydrogenation on the basis of such a aminofosfine and a overgangsmetaal.

摘要

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@(NR2R3)3-x where R1, R2 and R3 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 (R3R2N)nX and a coordination compound of a metal from the transition series.
