Aerobic epoxidation of hindered olefins and enol ethers catalyzed by a polymerizable β-ketoesterate complex of iron(III)

Abstract

Peculiar hindered olefins and derivatives have been epoxidized, under Mukaiyama's conditions, using iron(III) catalytic centres. The experimental results allow to rule out the involvement of singlet oxygen and free peroxyacids as active species.
