[((R,R)-2-Amino-1,2-diphenylethyl)[(4-tolyl)sulfonyl]amido](chloro)( p -cymene)ruthenium(II)

Application

The purpose of [((R,R)-2-Amino-1,2-diphenylethyl)[(4-tolyl)sulfonyl]amido](chloro)(p-cymene)ruthenium(II) is to serve as a highly effective catalyst for enantioselective hydrogenation processes. This catalyst, appearing as an orange to brown powder, utilizes phosphine cationic ruthenium complexes to achieve precise enantioselective reactions. It is particularly efficacious in the hydrogenation of various substrates, such as quinolines, N-alkyl ketimines, and antitumor and antiproliferative derivatives of natural products sourced from bacteria. In addition, it is capable of catalyzing the hydrogenation of hydroxy arylaldehydes via the Rap-Stoermer enantioselective transfer hydrogenation method, and it is adept at handling functionalized ketones with substituents like dialkylamino, hydroxy, siloxy, carbonyl, ester, amide, or thioester. The performance improvements of this catalyst have been augmented through microenvironment engineering of nanocages, allowing for enhanced catalytic effectiveness. The chiral diamine ligand complexed with ruthenium, RuCl(p-cymene)[(R,R)-Ts-DPEN], underpins the superior enantioselectivity displayed in these reactions.
