(R)-(+)-2,2',6,6'-TETRAMETHOXY-4,4'-BIS(DI(3,5-XYLYL)PHOSPHINO)-3,3'-BIPYRIDINE Usage And Synthesis

Chemical Properties	White solid
Uses	(S)-(-)-2,2',6,6'-Tetramethoxy-4,4'-bis(di(3,5-xylyl)phosphino)-3,3'-bipyridine is used in Pharmaceutical and industry applications.
Uses	Ligand employed in the asymmetic hydrogenation of ?-keto esters, 2-arylacrylates, aryl ketones , and other substrates.
Reactions	Chiral ligand for the asymmetric hydrogenation of β-keto esters. Chiral ligand for enantioselective rhodium-catalyzed [2+2+2] carbocyclization reactions. Chiral ligand for ruthenium catalyzed hydrogenation of (E)-β-(acylamino)acrylates to β-amino acids. The Rhodium complex gives higher enantioselectivity for hydrogenation of (Z)-β-(acylamino)acrylates to β-amino acids. Chiral ligand for copper-catalyzed asymmetric hydrosilylation of ketones. Chiral ligand for asymmetric allylic substitution reactions using boronic acids as nucleophiles. Gives useful selectivity in asymmetric Pauson-Khand-type cyclizations.
