Chiral phosphorus compounds

Novel chiral phosphorus compounds of the formula STR1 wherein R signifies lower alkyl, R1 signifies phenyl and R2 and R3 signify hydrogen or lower alkoxy, which are suitable in the form of complexes with a metal of Group VIII as catalysts for asymmetric hydrogenations and for enantioselective hydrogen displacements in prochiral allylic systems.

Axially Dissymmetric Diphosphines in the Biphenyl Series: Synthesis of (6,6'-Dimethoxybiphenyl-2,2'-diyl)bis(diphenylphosphine) ('MeO-BIPHEP') and Analogues via an ortho-Lithiation/Iodination Ullmann-Reaction Approach

The new axially dissymmetric diphosphines (R)- and (S)-(6,6'-dimethoxybiphenyl-2,2'-diyl)bis(diphenylphosphine) ((R)- and (S)-5a; 'MeO-BIPHEP') and the analogues (R)- and (S)-5b and 5c have been synthesized in enantiomerically pure form.These lignands hav
