During the last decade new strategies in chemical reaction engineering evolved in order to facilitate the handling as well as to improve the efficiency of chemical reactions (Facilitated Synthesis). These developments are mostly dedicated to meet the requirements of “Green Chemistry”. One important issue in this field of research deals with techniques for efficient catalyst separation and recycling. Catalyst immobilization on polymeric scaffolds provides not only improved catalyst stability and solubility, but also an easy workup including filtration or zentrifugation techniques. Additionally, the implementation of stimuli-sensitive polymeric carriers offers the possibility of controlling the reaction progress by altering environmental conditions. Utilizing micelles as nanoreactors provides the possibility to conduct chemical reactions in aqueous media under mild conditions. Organocatalysis has developed to be a valueable tool for asymmetric synthesis of complex molecules. Nevertheless, relatively large amounts of catalyst are usually required to obtain high yields as well as good stereoselectivity. Once the reaction is finished, this large amount of organocatalyst needs to be elaborately separated. In the present work several temperature-responsive block copolymers were synthesized using a controlled radical polymerization technique (ATRP). These block copolymers are potentially useful as polymeric catalyst carriers for micellar catalysis. Furthermore a polymerizable derivate of an organocatalyst based on L-proline was obtained after a three-step synthesis and incorporated into the temperature-responsive block by controlled radical copolymerization. The synthesized block copolymers showed temperature-induced aggregation forming potential nanoreactors for micellar catalysis.
