Recent emerging applications of chromium porphyrin complexes are generating increasing interest in oxidation chemistry and catalysis. Its recent application as metal-organic frames in spintronic devices supports the rich electronic system of chromium metal. Through the past decades, first-row transition metalloporphyrins have served as biomimetic oxidation catalysts and models of cytochrome P450 enzymes. However, the oxygen atom transfer mechanism of chromium porphyrin complexes, most especially in sulfide oxidation reactions, has been scarcely investigated.
In this study, high-valent chromium-oxo porphyrin species, namely CrIV-oxo and CrV-oxo species, with electron-donating tetramesitylporphyrin(TMP) ligand were successfully generated and characterized with UV-vis, ESI-MS, …
