Mn(III)-, Fe(III)-porphyrin Catalyzed Oxidation of cycloolefins

The catalytic oxidations of several cycloolefins in $CH_2Cl_2$ 수식 이미지 were been investigated using Mn(III)-, Fe(III)-porphyrin complexes as a catalyst and sodium hypochlorite as a terminal oxidant. Porphyrins were $(p-CH_3O)TTP,\;(p-CH_3)TTP,$ 수식 이미지 TPP, (p-F)TPP, (p-Cl)TPP and $(F_{20})TPP$ 수식 이미지 (TPP = tetraphenylporphyrin), and olefins were cyclopentene, cyclohexene and cycloheptene. The substrate conversion yield was discussed according to the substituent effects of metalloporphyrin. The conversion yield of substrate by changing the substituent of TPP increased in the order of $p-CH_3O$ 수식 이미지 < $p-CH_3$ 수식 이미지 < H < p-F < p-Cl, which was consistent with the sequence of $4{\sigma}$ 수식 이미지 values of TPP. The conversion of cycloalkene followed the order of $C_5\; 수식 이미지<\;C_6\; 수식 이미지<\;C_7$ 수식 이미지.
