Metal-capped α-cyclodextrins: the crowning of the oligosaccharide torus with precious metals

New Phosphane Based on a β‐Cyclodextrin, Exhibiting a Solvent‐Tunable Conformation, and its Catalytic Properties

“…Characterisation and structure determinations were achieved by NMR spectroscopy experiments by using a Bruker Avance DRX300 spectrometer operating at 300. 13 31 P NMR) and calibration was performed by using the signal of the residual signals of the solvent as a secondary reference while taking into account temperature effects. The MALDI-TOF mass spectra were recorded on a MALDI-TOF-TOF Bruker Daltonics Ultraflex II spectrometer in positive reflectron mode by using 2,5-dihydroxybenzoic acid as a matrix and external peptide calibration standard kit (Bruker Daltonics) within a mass range of 750-4200.…”

Synthesis, Rhodium Complexes and Catalytic Applications of a New Water‐Soluble Triphenylphosphane‐Modified β‐Cyclodextrin

“…Nevertheless, only some of CD-phosphanes were exploited in aqueous organometallic catalytic processes. [4][5][6][7][8] In this context, we have recently reported the synthesis of a new, highly water-soluble diphenyl monophosphane permethylated-b-CD (PM-b-CD-PPh 2 ; Figure 1). [9] A self-inclusion of a phenyl group of the phosphane moiety into the CD cavity was observed.…”

Chemistry of metalated container molecules

“…In recent years, the development of metalated container molecules has become an attractive research goal [16][17][18] because such compounds allow for an interplay of molecular recognition and transition-metal catalysis [19,20]. Consequently, a number of research groups are involved in the development of new receptor molecules that create confined environments about active metal coordination sites.…”
