Structural factors, which govern the chemical stability of metallo-tetraaryl porphyrins, were investigated in CH2Cl2/H2O two-phase alkene epoxidations promoted by aqueous NaOCl or 30percent H2O2. In contrast to recent literature reports, the perhalogenati

The N-bromosuccinimide bromination of the zinc derivative of meso-tetramesitylporphyrin, Zn(TMP), in methanol at reflux in air, gives the corresponding (β-pyrrole)octabromo derivative, meso-tetramesityl-β-octabromoporphyrinatozinc, Zn(Br8TMP), in high yield (60-75%). Furthermore, the sulfonation by oleum of the metal-free ligand gives the persulfonated porphyrin, meso-tetrakis(3,5-disulfonatomesityl)-β-octabromoporphyrin, Br8 TMPSH2 (70-75%). These robust manganese and iron derivatives are efficient catalysts in oxygen atom or electron transfer reactions.
