Biomimetic approach to lignin degradation II. The mechanism of oxidative C-C bond cleavage reactions of lignin model compounds with natural iron (III) porphyrin chloride as a hemeenzyme model system

Biomimetic approach to lignin degradation II. The mechanism of oxidative C-C bond cleavage reactions of lignin model compounds with natural iron (III) porphyrin chloride as a hemeenzyme model system

Biomimetic oxidation of lignin model compounds such as ß-1, ß-O-4, and ß-5 Substrates was investigated with a natural ironprophyrin which mimicks the ligninase catalysis. 18O from molecular oxygen and water were found to be incorporated, to different degrees, into the C-C bond cleavage product (pmet...
