Activation, Tuning, and Immobilization of Homogeneous Catalysts in an Ionic Liquid/Compressed CO(2) Continuous-Flow System This work was supported by the Max Planck Society, the DFG (Gerhard-Hess-Award to W.L.), and the Fonds der Chemischen Industrie. The fruitful input of Dipl.-Chem. Heike Stemmer and Dr. Andreas Wegner (both Mülheim) during the early phase of the project is gratefully acknowledged.
