Mesopore immobilised copper bis(oxazoline) complexes for enantioselective catalysis

New supported heterogeneous catalysts have been synthesised through the tethering of copper bis(oxazoline) complexes to the surfaces of MCM-41 and MCM-48 mesoporous materials, and the prepared catalysts shown to be highly active in the enantioselective cyclopropanation of styrene with ethyl diazoacetate.
