Asymmetric catalytic 1,2-dihydrophosphination of secondary 1,2-diphosphines - direct access to free P*- and P*,C*-diphosphines
A 1,2-dihydrophosphination of bis(phenylphosphino)ethane with a wide range of activated olefins was achieved in a catalytic manner with enantiomeric and diastereomeric excess of up to >99% and 44% respectively. The protocol can be extended to selected substrates leading to free P- and C-chiral 1,...

| description | A 1,2-dihydrophosphination of bis(phenylphosphino)ethane with a wide range of activated olefins was achieved in a catalytic manner with enantiomeric and diastereomeric excess of up to >99% and 44% respectively. The protocol can be extended to selected substrates leading to free P- and C-chiral 1,2-diphosphines. The synthesized ligands can also undergo direct complexation onto palladium affording complexes with complete retention of stereo-integrity. (Figure presented.). |
