Superhydrophobic, chiral, and mesoporous TsDPEN copolymer coordinated to ruthenium species as an efficient catalyst for asymmetric transfer hydrogenation

Homogeneous chiral catalysts usually show higher catalytic activities than corresponding heterogeneous chiral catalysts, because of their easy interaction between catalytically active sites with reactant molecules. We demonstrate here superhydrophobic, chiral, and mesoporous catalysts (TsDPEN-Ru) synthesized from copolymerization of N-p-styrenesulfonyl-1,2-diphenylethylenediamine (V-TsDPEN) with divinylbenzene and loading of Ru species exhibiting much higher activities in asymmetric transfer hydrogenation (ATH) of ketones in aqueous solution than corresponding homogeneous chiral catalyst. This phenomenon is strongly related to the unique features of high enrichment for the reactants in superhydrophobic TsDPEN-Ru catalysts due to their good wettability, as well as easy transfer of product from the catalyst into water phase. These features open a door for design and developing a wide variety of chiral catalysts for asymmetric catalysis.

Preparation of microgel-supported chiral catalysts and their application in the asymmetric hydrogenation of aromatic ketones

An enantiomerically pure chiral monomer (S,S)-2 was prepared and copolymerized with styrene and four different cross-linkers to produce four distinct microgel-supported chiral TsDPEN derivatives. These chiral copolymers were allowed to form complexes with
