Adsorption of a cyclic amine ligand into a Mn‐exchanged faujasite zeolite results in the formation of the corresponding amine—Mn complexes in the cavities of the zeolite. These “amine—Mn zeolites” are novel catalysts for the highly selective epoxidation of numerous olefins with H 2 O 2 . A computer model of a possible catalytically active species, a Mn III /Mn IV complex with bridging oxygen ligands, is shown on the right.
