MCM-41상에 고정화된 키랄살렌의 광학선택적 촉매활성

초록

The chiral salen complexes immobilized on mesoporous material were applied as catalysts in the epoxidation of olefins, and the reduction of aromatic ketone, addition of trimethylsilylcyanide to benzaldehyde. According to our studies, unsymmetrical chiral salens immobilized on MCM-41 represented relatively high ee% for this reaction. The enantioseletive hydrolytic resolution of racemic epoxides was performed in the ZSM-5/MCM-41 membrane system containing chiral salen complexes.
