L. Lopez et al., AEROBIC EPOXIDATION OF HINDERED OLEFINS AND ENOL ETHERS CATALYZED BY A POLYMERIZABLE BETA-KETOESTERATE COMPLEX OF IRON(III), Tetrahedron letters, 35(21), 1994, pp. 3633-3636
Peculiar hindered olefins and derivatives have been epoxidized, under
Mukaiyama's conditions, using iron(III) catalytic centres. The experim
ental results allow to rule out the involvement of singlet oxygen and
free peroxyacids as active species.
