Remarkable effciency of iron(III) versus manganese(III) tetraphenylporpyrins as catalysts for fast and quantitative oxidation of sulfides into sulfones by hydrogen peroxide

Remarkable effciency of iron(III) versus manganese(III) tetraphenylporpyrins as catalysts for fast and quantitative oxidation of sulfides into sulfones by hydrogen peroxide

The efficiency of various metallo-phtalocyanines (Pht) and -tetraphenylporphyrins (TPP) as catalysts for the H2O2 oxidations of dibenzylsulfide, phenylchloroethylsulfide, and thioanisole is investigated in ethanol and acetonitrile, using imidazole as a cocatalyst. Neither PhtNiII nor TPPCoII exhibit...
