Noble metal nanoparticles have been successfully used as catalysts in the hydrogenation of high molecular weight polymers. For example, rhodium nanoparticle/nanopowders have shown extremely high activity and good selectivity in hydrocarbon hydrogenation.
The olefin double bond is often adjacent to a larger functional group—hydrocarbon group, which makes it difficult to open the double bond. With the addition of 20nm rhodium powder, it is easy to open the double bond and make the hydrogenation reaction smoothly.
Olefins that can be catalyzed by nano rhodium include 1-hexene, cyclohexene, 2-hexene, butenone, mesityl oxide, methyl acrylate, methyl methacrylate, and cyclooctene, among others. Different particle sizes have an effect on catalytic activity. Generally, the smaller the particle size, the faster the hydrogenation rate.
Henan Normal University and the Institute of Chemistry, Chinese Academy of Sciences have cooperated to develop a new method for asymmetric catalytic synthesis of a class of chiral acyclic nucleoside compounds. Using a complex formed by nano rhodium(Rh) and a chiral bisphosphine ligand (R)-BINAP as a catalyst, a series of side chains were prepared by asymmetric hydrogenation of α-purine-substituted acrylates at room temperature and pressure. Acyclic nucleosides containing a chiral group at the 1′ position. Nucleoside compounds have a wide range of biological activities, are an important class of drugs and drug intermediates, occupy an important position in anti-tumor, anti-viral and anti-AIDS drugs, and are currently recognized as the most anti-viral potential drugs. .
