Zusammenfassung: | The invention is concerned with novel water-soluble racemic or optically active compounds of formulae wherein R ,R , R and R independently signify lower alkyl or lower alkoxy; m and n are 0, 1 or 2; X signifies hydrogen, an alkali metal, the equivalent of an earth alkali metal or an ammonium ion; with the provisio that R and R are not located at postion 3 or 3'. The invention is also concerned with a process for the manufacture of such compounds, complexes of such compounds with a metal of Group VIII and with the use of these complexes as catalyst for asymmetric hydrogenation and for enantioselective hydrogen displacement in prochiral allylic systems. |
