The Catalytic Function of Nonheme Iron (III) Complex for Hydrocarbon Oxidation

[摘要] A detailed catalytic study ofLFeIIICl(whereL=3-{2-[2-(3-hydroxy-1,3-diphenyl-allylideneamino)-ethylamino]-ethylimino}-1,3-diphenyl-propen-1-ol) for hydrocarbon oxidation was carried out, focusing on the role of solvent, atmospheric dioxygen, and oxidant on catalytic efficiency. The data showed thatLFeIIIClcatalyst was efficient in homogeneous hydrocarbon oxidations providing significant yields. Moreover,tert-BuOOH provided comparable oxidation yields withH2O2, slightly favoring the formation of alcohols and ketonesversusepoxides. Dioxygen intervened in the catalytic reaction, influencing the nature of oxidation products. The polarity of solvent strongly influenced the reaction rates and the nature of oxidation products. A mechanistic model is postulated assuming thatLFeIIIClfunctionsviathe formation of iron-hydroperoxo-species, followed by a radical-based mechanistic path.
