Nano SiO2-bonded Ru-TsDPEN for catalytic resolution of 1,2-propanediol by two transfer hydrogenation
A new strategy was introduced for the catalytic resolution of 1,2-propanediol involving the successive oxidative kinetic resolution and asymmetric hydrogenation by two hydrogen transfer reactions catalyzed by nano SiO2-bonded Ru-TsDPEN [TsDPEN = N-(p-toluenesulfonyl)-1,2-diphenylethylene diamine]-derived catalysts composed of two opposite configurations. The catalysts were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), Brunauer-Emmett-Teller (BET), Fourier-transform infrared spectroscopy (FT-IR), thermogravimetry-derivative thermogravimetry (TG-DTG) analysis, and inductively coupled plasma atomic emission spectrometry (ICP-AES). Results showed that Ru-TsDPEN derived catalysts were successfully grafted on the nano SiO2, affording high catalytic conversions of >99 and 99%, selectivities of 47 and 98% and maximum ee values of >99 and >99% in the two reactions, which were due to the nano SiO2 with Ru-TsDPEN in the reaction system with high dispersion. Additionally, the catalysts exhibited excellent durability and were filtered and reused at least five times without noticeable catalysts deactivations.
Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. Keep reading other articles of 4254-15-3! Product Details of 4254-15-3
