Abstract: The highly efficient aerobic oxidation of alcohols to carbonyl compounds was achieved catalyzed by cationic meso-tetrakis (1-methyl-4-pyridyl, TM4PyP) metalloporphyrins immobilized in montmorillonite interlayers. Cobalt porphyrin (CoTM4PyP-MT) showed excellent activity and selectivity in the aerobic oxidation of benzyl alcohol, where 90% yield of benzaldehyde was obtained. CoTM4PyP-MT can be five times reused without significant loss of activity.
