Straightforward Synthesis of Poly(dimethylsiloxane) Phases with Immobilized (1R)‐3‐(Perfluoroalkanoyl)camphorate Metal Complexes and Their Application in Enantioselective Complexation Gas Chromatography (Eur. J. Org. Chem. 21/2012)

Abstract

The cover picture shows the leaves and blossom of the camphor tree cinnamomum camphora (photo taken at the botanical garden of the Ruprecht Karls University Heidelberg), a natural source of (+)‐(1R)‐camphor, which is the chiral key moiety of immobilized (1R)‐3‐(perfluoroalkanoyl)camphorate metal complexes. The beautiful white blossom forms a structure with tetrahedral elements, which are “mirrored” in the model of the polymeric chiral stationary phase. This chiral stationary phase is accessible in large quantities and can be used in complexation gas chromatography, showing exceptional high separation factors for a large number of stereoisomers. Details are discussed in the article by O. Trapp et al. on p. 3929 ff.
