Abstract

The synthesis of the petroporphyrins (3e) and (4e) has been completed, and their presence as the nickel complexes (3a) and (4a) in the Julia Creek shale oil deposits has been confirmed. While the derivation of (4e) from a chlorophyll c is generally accepted, it is proposed that (3e) may also originate from this group of pigments, thus highlighting the importance of these photosynthetic pigments as a source for fossil porphyrins.
