| Abstract: | Three complexes of tetrachlorophenylporphyrinatomanganese acetates have been synthesized and characterized by IR and UV spectra. The asymmetric epoxdation of styrene has been investigated by using these three complexes as catalysts, chiral quaternary ammonium salts as phase transfer catalysts, and quinine as chiral auxiliary, sodium hypochlorite as oxidant. The results showed that the structure of manganese porphyrins, the chiral auxiliaries and temperature of reaction affected the asymmetric induction. The best enantiomer excess reached 12 8%. |
