NEW ORTHO-FUNCTIONALIZED P-CHIRAL ARYLPHOSPHINES AND DERIVATIVES: THEIR PREPARATION AND USE IN ASYMMETRIC CATALYSIS

The invention relates to novel organo phosphorus P-chiral optically active compounds of formula (I) having a hydroxyl, mercapto, amino, carboxyl, sulfonyl group on aryl near a phosphorus atom, to the preparation and the use thereof in then asymmetrical catalysis of unsaturated compounds. Novel acylphosphine optically pure ligands embodied in the form of transition metal complexes exhibit an increased activity and enantloselectivity, in particular in asymmetrical hydrogenation, in comparison with the same type Uganda such as DiPAMP.

Heavyweight "R-SMS-Phos" ligands in the olefins' hydrogenation arena

"Chemical Equation Presented" A serles of enantiopure P-stereogenic 1,2-bis[(o-RO-phenyl)(phenyl)phosphino]ethane (R-SMS-Phos) ligands wherein R= i-Pr, i-Bu, tf-Bu, 3-Pen, and CH2TMS was assessed in the Rh(l)-catalyzed hydrogenation of an indic
