Grasa, Gabriela A.; Zanotti-Gerosa, Antonio; Hems, William P. published the article 《A chiral [(dipyridylphosphine)RuCl2(1,3-diphenylpropanediamine)] catalyst for the hydrogenation of aromatic ketones》. Keywords: hydrogenation transfer stereoselective ruthenium catalyst preparation ketone; phenylphosphine bipyridine ruthenium propanediamine preparation transfer hydrogenation catalyst; asym synthesis phenylphosphine bipyridine ruthenium propanediamine preparation.They researched the compound: (R)-2,2′,6,6′-Tetramethoxy-4,4′-bis(diphenylphosphino)-3,3′-bipyridine( cas:221012-82-4 ).Name: (R)-2,2′,6,6′-Tetramethoxy-4,4′-bis(diphenylphosphino)-3,3′-bipyridine. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:221012-82-4) here.
The use of chiral (+)-(S,S)-1,3-Diphenyl-1,3-propanediamine in combination with Ru-Xyl-P-Phos, gave up to 95% ee in the hydrogenation of acetophenone. Thus, [(3R)-4,4′-bis[bis(3,5-dimethylphenyl)phosphine]-2,2′,6,6′-tetramethoxy-3,3′-bipyridine]dichloro[(1S,3S)-1,3-diphenyl-1,3-propanediamine]ruthenium was prepared and its catalytic activity and selectivity were compared with its corresponding stereoisomers.
I hope my short article helps more people learn about this compound((R)-2,2′,6,6′-Tetramethoxy-4,4′-bis(diphenylphosphino)-3,3′-bipyridine)Name: (R)-2,2′,6,6′-Tetramethoxy-4,4′-bis(diphenylphosphino)-3,3′-bipyridine. Apart from the compound(221012-82-4), you can read my other articles to know other related compounds.
