The　aerobic　oxidation　of　alkylaromatics　to　aromatic　ketones　catalyzed　by　metalloporphyrins　under　the　special　temperature　control　method　was　systematically　investigated.　Three　novel　and　key　points　were　found　to　have　significant　functions　in　this　process,　that　is,　the　special　temperature　control　method　(initiation　at　higher　temperature　and　reaction　at　lower　temperature),　the　synergistic　effect　of　the　composite　catalysts　comprising　cobalt　and　manganese　porphyrins,　and　the　amount　of　catalysts　in　the　reaction.　Subsequently,　the　effects　of　substitutes　on　alkylaromatics　were　also　explored　under　the　same　conditions.　Results　showed　that　alkylaromatic　conversions　gradually　increased　from　8.5%　to　54.3%　with　the　para-substituents　shifting　from　the　electron-donating　group　to　the　electron-withdrawing　group　(i.e.,　methoxy　＜　hydro　＜　bromo　＜　acyl　＜　nitro).　A　possible　mechanism　for　this　reaction　was　also　proposed.
