摘要

With μ-oxo dimeric iron (III) porphyrins [(FeIIITPP) 2O] as catalyst, isobutylaldehyde as co- reductant, and dioxygen as oxidant, an efficient model system for epoxidation of olefins has been developed. Compared with mono-metalloporphyrins as catalyst, a remarkable enhancement of reactivity was obtained for the present olefin epoxidation system, in which the turnover number (TON) of the catalyst has doubled from about 700 million to 1400 ...
