Abstract

Ionic liquids, combinations of organic cations and anions, are structured media of several nanometers and have very interesting and flexible properties. Thanks to these properties, ionic liquids have found a place in abundant applications, particularly in organic synthesis. In this thesis we have presented three different uses: i) The first use is based on the use of ILs as a controlled ring-opening polymerization (POC) catalyst for -caprolactone under mild condition. ii) The second use of ionic liquids is based on the synthesis of an innovative organotin catalyst / initiator supported on an ionic liquid for the preparation of a biodegradable polymer. The presence of the IL should make possible the elimination of the catalyst by simple fil...
