Low amount of manganese meso-tetraphenyl porphyrin [Mn(TPP)] was used for highly efficient selective oxidation of sulfide to sulfone by hydrogen peroxide at room temperature. Sulfones were produced directly with yields generally around 90% while the catalyst concentration was only 4×10−5 mol·L−1. In a large-scale experiment of thioanisole oxidation, the isolated yield of sulfone (87%) was obtained and the turnover number (TON) reached up to 8×106, which is the highest TON for the oxidation systems of sulfide to sulfone catalyzed by metalloporphyrins.

A facile, substrate-selective and transition metal-free oxidation of benzylic and allylic alcohols catalyzed by β-cyclodextrin with NaOCl oxidant using water as an only solvent was developed.

Highly efficient epoxidation of olefins by molecular oxygen with catalytic amount of manganese meso-tetraphenylporphyrin (Mn(TPP)) at the ppm level were reported. The catalyst conferred high activity and selectivity for the olefins epoxidation under ambient temperature and atmospheric pressure. The turnover number (TON) of the catalyst could reach up to 700 million, which is comparable to enzyme catalysis.
