Abstract

Zinc hydroxyisoporphyrin (2), under sunlight and argon, is reduced back to zinc meso-tetraphenylporphyrin (1), but stays stable in oxygen in the absence of light. This behavior is in contrast to its iron analogue and stresses the redox role of iron in heme degradation. Compound 2 also responds to chlorophyll-type degradation (3) under sunlight and oxygen.
