Chiral diphosphites and diphosphoramidites derived from BINOL or diphenylprolinol are efficient ligands in asymmetricRh-catalyzed olefin hydrogenation, provided the proper achiral backbone is chosen.
Phosphoramidites with the general formulae I to VI are claimed together with the use of these compounds as ligands of transition metal compounds, in particular in transition metal catalysts, in the hydrogenation, transfer hydrogenation, hydroboration, hydrocyanation, 1,4-addition, hydroformylation, hydrosilylation, hydrovinylation, and Heck reactions of prochiral olefins, ketones, or ketimines.
