An efficient approach for aromatic epoxidation using hydrogen peroxide and Mn(III) porphyrins

摘要

Efficient epoxidation, in very high conversions and selectivities, of aromatic hydrocarbons with hydrogen peroxide, in the presence of Mn~(III) porphyrins [Mn(TDCPP)Cl, Mn(βNO_2TDCPP)Cl, Mn(TPFPP)Cl] as catalysts is described; naphthalene and anthracene afford the anti-1,2:3,4-arene dioxides whereas with phenanthrene the 9,10-oxide is obtained.
