WebThe fascinating structures of naturally occurring porphyrins and metalloporphyrins have been perfected by nature to give functional dyes par excellence. The important roles these tetrapyrrolic macrocycles play in vital biological processes, in particular photosynthesis (chlorophyll), oxygen transport (hemoglobin), oxygen activation (cytochrome), have led to … WebMetalloporphyrins containing the TPP ligand are called the first-generation metalloporphyrin catalysts. Although the first-generation metalloporphyrins associated with artificial oxidants such as PhIO, NaOCl, and KHSO 5 mimicked much of the chemistry of cytochrome P450, their catalytic activities became rapidly diminished by the extensive …
