Efficient oxidative decarboxylation of carboxylic acids with sodium periodate catalyzed by supported manganese (III) porphyrin

Oxidative decarboxylation of carboxylic acids by a supported manganese (III) porphyrin was investigated. In the chemical system using 5,10,15,20-tetrakis(4-aminophenyl)porphyrinatomanganese (III) chloride supported on crosslinked chloromethylated polystyrene, [Mn(H2NTPP)-CMP], as catalyst, carboxylic acids are converted to the corresponding carbonyl compounds via oxidative decarboxylation with sodium periodate.
