Recoverable, Soluble Polymer-Supported Organic Catalysts, ligands and catalysts. This chapter highlights the more recent results obtained by our group in the field of poly(ethylene glycol) (PEG)-supported chiral and achiral organic catalysts. A?few considerations on the methodologies, the future and the problems related to the immobilization of chiral organic catalysts are also briefly discussed.
