(+)-1,2-BIS((2S,5S)-2,5-DIPHENYLPHOSPHOLANO)ETHANE(1,5-CYCLOOCTADIENE)RHODIUM (I) TETRAFLUOROBORATE

Reaction

1. Phenyl-BPE exhibits enhanced activity and selectivity over existing members of the BPE ligand family in rhodium catalysed asymmetric hydrogenation.
2. This ligand is highly efficient for the hydrogenation of N-acyl aryl-enamides.
3. Molar substrate/catalyst ratios of up to 100,000/1 are achieved with excellent reactivity and enantioselectivity using commercial grade substrates and solvents.
4. Ligand in the rhodium-catalyzed asymmetric hydroformylation of olefins.
