Cycloolefins Oxidation Reaction Catalyzed by Ga(III)-, In(III)- and TI(III)-Porphyrin Derivatives

The catalytic oxidation reaction of several cycloolefins in CH2Cl2 have been investigated using non-redox metalloporphyrin(M = Ga(III), In(III) and TI(III) complexes as a catalyst and sodium hypochlorite as a terminal oxidant. Porphyrins were (p-CH3O)TPP, (p-CH_3)TPP, TPP, (p-F)TPP, (p-Cl)TPP and (F{20})TPP (TPP=5,10,15,20-tetraphenyl-21H,23H-porphyrin) and olefins were cyclopentene, cyclohexene, cycloheptene and cyclooctene, The substrate conversion yield(%) was investigated according to the radius effect of non-redox metal ion, substituent effect and hindrance effect of metalloporphyrin. The conversion yield of cycloolefin was in the following order : C5 < C6 < C7 =C8.
