主 题:metalloporphyrins olefins dioxygen epox-idation
摘 要:The epoxidation of linear terminal olefins with metalloporphyrins in the presence of dioxygen and isobutyraldehyde under ambient temperature and atmo-spheric pressure was *** results show that all olefins could be smoothly converted to epoxides with high selectivities(70%–90%).For the metalloporphyrins with different catalytic activities within 1-hexene epoxidation in the order of FeMnCo,T(o-Cl)PPFe(III)Cl was most effective,with a 41.7%yield and 80.2%selectivity of 1,*** amounts of catalyst were investi-gated,and it was found that with only 10ppm catalyst the yield of 1,2-epoxyhexane and turnover number(TON)could reach up to 41.9%and 41859,respectively.
