Adsorption of 1-(1-Naphthyl)ethylamine from Solution onto Platinum Surfaces: Implications for the Chiral Modification of Heterogeneous Catalysts

摘要

Since Orito et al. reported that the hydrogenation of prochiral molecules using transition-metal heterogeneous catalysts may be made enantioselective by adding a small amount of a chiral modifier to the liquid reaction mixture, there has been a great deal of interest in understanding how this chiral modification works and in extending it to other systems. Unfortunately, it has been difficult to identify other types of chiral modifiers beyond the cinchona alkaloids and related molecules used in the initial studies. A better knowledge of the molecular mechanism that accounts for these reactions may be needed to expand the library of viable chiral modifiers. This has also become a prototypical system for the investigation of possible chiral modification of heterogeneous catalysts in general.
