Immobilized Cu(II) complexes within montmorillonite and MCM-41 successfully catalize the epoxidation of norbornene and trans-2-hexene-1-ol. ▪ Copper(II) complexes with 2,2′-bipyridine(bpy) and 1,8-dibenzyl-1,3,6,8,10,13-hexaazacyclotetradecane (macrocycle) immobilized between silicate layers of montmorillonite and nanoreactors of MCM-41 successfully catalyze the epoxidation of norbornene and trans-2-hexene-1-ol with good to excellent reactivity and 48–100% selectivity toward the formation of the corresponding epoxides.
